1. What is an excavator engine block?

The excavator engine block is the skeleton of the engine and serves as the assembly base for the crankshaft, connecting rod mechanism, valve train, and other major components of the engine systems.

The diesel engine cylinder block is a crucial component of your excavator engine, often overlooked until problems arise. Not only does it withstand the force of high-temperature, high-pressure gases, but almost all of the engine’s components are mounted on the cylinder block. Therefore, the cylinder block must have sufficient strength and rigidity to ensure the normal operation of the engine.

When the engine cylinder block is damaged, how should we repair it? Two simple steps will teach you how to repair the engine cylinder block.

2. How to repair a damaged engine cylinder block?

(1) Cylinder block deformation repair

Inspection method: Scrape all the liner materials on the surface of the cylinder block, and use a precision straightedge and a thickness gauge to measure whether there is any warpage on the surface contacted by the cylinder head liner. Place the straightedge on the upper plane of the cylinder block, and use the thickness gauge to measure the clearance between the straightedge and the upper plane of the cylinder.
Repair method: cylinder block unevenness is small, can be scraped repaired; unevenness is larger, can be milling process. But the amount of trimming shall not exceed 0.30mm; otherwise, the cylinder block should be replaced.

(2) Cylinder block crack repair

Inspection method: hydrostatic test of the cylinder block to check whether there are cracks. Inspection, the first according to the specified requirements of the cylinder head and cylinder block, and block the necessary water inlet and outlet channels, and then connected to the water compressor outlet pipe, the water temperature of 60-70 ℃, water pressure of 392kPa, duration of 3min, any part of the cylinder block shall not have leakage or wet phenomenon.
Repair method: generally use the welding method and the glue repair method.

The post How to repair a damaged engine cylinder block? appeared first on SicomcnParts.

1. High-pressure fuel supply

The high-pressure pump pressurizes the fuel and sends it to the common rail pipe. The injector is connected to the common rail through the fuel pipe and remains in a high-pressure state, ready for injection.

2. ECU control signal

The ECU calculates the injection timing and duration according to the sensors (crankshaft position, camshaft position, load, etc.), and sends a pulse signal to the injector solenoid valve.

3. The injecting process

Opening stage: the solenoid valve is energized, the control valve opens, the high-pressure fuel pushes the needle valve up, and the injection hole opens.

Injection stage: The fuel is atomized and sprayed from the injection hole with very high pressure, and the amount of fuel injected is determined by the pulse width of the ECU.

Closing stage: the solenoid valve is de-energized, the control valve is reset, the needle valve is rapidly closed under the action of spring force, and the fuel injection is terminated.

4. Multi-stage injection

Modern Cummins engines may use multiple injections (e.g., pre-injection to reduce combustion noise, main injection to ensure power, and post-injection to reduce particulate matter).

The post How a diesel fuel injector works? appeared first on SicomcnParts.

What does a diesel fuel injector do?

1. Fuel Atomization

Converts high-pressure fuel into extremely fine mist-like droplets through tiny spray holes, increasing the contact area with air to ensure full combustion.

2. Precision Metering

Controls the amount of fuel injected each time according to the instruction from the engine control unit (ECU), matching the demand under different working conditions (e.g., idling, acceleration, high load, etc.).

3. Timed Injection

Injects fuel strictly according to the injection timing calculated by the ECU (e.g., pre-injection, main injection, post-injection), optimizing the combustion process and reducing noise and emissions.

4. Pressure Maintenance

Maintains a stable high pressure (up to 2000 bar or more) in the common rail system to ensure the atomization effect and injection speed.

Structural Components of an Injector

Cummins injectors usually contain the following key components:

Solenoid valve/piezoelectric crystal: receives signals from the ECU to quickly turn fuel injection on/off.

Needle valve: rises under high-pressure fuel push and fuel is injected; resets and closes after pressure drops.

Spray holes: Precision-machined micro-holes (about 0.1mm in diameter), affecting the shape of atomization and penetration.

High-pressure fuel line: connected to the common rail system and subject to extreme pressure.

Return passage: Discharges leaking fuel and maintains system pressure balance.

1. Exhaust gas drives the turbine.

The exhaust gases emitted by the engine possess inertial momentum, which propels the turbine to rotate.

2. The turbine drives the impeller.

The rotation of the turbine drives the coaxial impeller, which compresses the air supplied through the air filter pipe, forcing it into the cylinders at a higher pressure.

3. Increases air intake.

As engine RPM increases, the exhaust gas flow rate and turbine speed also increase synchronously. The impeller compresses more air into the cylinders, increasing air pressure and density, enabling the combustion of more fuel.

4. Enhancing engine power.

By increasing air intake, the engine can inject more fuel, thereby boosting engine power. Engines equipped with a turbocharger typically see a 20%–30% increase in power and torque.

1.What is engine cylinder pulling?

Cylinder pulling is a professional term for engine maintenance. Engine cylinder pulling refers to the inner wall of the cylinder in the piston, piston ring movement range, there is a clear longitudinal or mass of mechanical scratches and scuffing, serious fusion wear occurs. In other words, the interruption of the oil film between the piston and the cylinder liner is the main reason for cylinder pulling. Once the oil film between the piston and the cylinder liner is interrupted, the two metals produce dry friction, resulting in cylinder pulling.

2. What are the hazards of engine pulling?

Abnormal engine noise, oil pressure too low, engine oil passage is clogged, will cause the engine under the exhaust serious, the pressure inside the engine crankcase increases, and in serious cases, it will cause an explosion inside the engine crankcase.

3. What causes the cylinder pulling?

The main reasons for cylinder pulling are as follows:
(1)The piston ring clearance is too small. If the piston ring opening clearance, side clearance or backlash is too small, the engine works when the piston ring thermal expansion jammed, and the cylinder wall pressure is very tight, or piston ring fracture, it is easy to pull out grooves in the cylinder wall.

(2)The piston pin out. Due to the piston pin spring is not installed or fall off, broken, the piston pin in the movement out, it is easy to pull the cylinder wall, resulting in cylinder gas to the crankcase.
(3)The piston cylinder clearance is too small or too large. If the material of the piston is bad, the manufacturing size error is too large, or the piston is deformed after assembling the piston pin, resulting in the piston and cylinder mating clearance is too small, the piston is stuck after thermal expansion, which in turn pulls the cylinder wall.
(4)Serious carbon buildup on the piston ring. Excessive carbon deposits caused by the piston ring bonding or bite dead in the ring groove, while carbon is a hard abrasive, will be ground into longitudinal grooves in the cylinder wall.

(5)The piston is seriously off-cylinder. Due to the connecting rod bending and twisting deformation, connecting rod journal, the main shaft neck, piston pin seat parallelism and coaxiality deviation is too large, caused by the piston obvious cylinder, will accelerate the piston ring, piston and cylinder wall wear, damage to the formation of the oil film.
(6)The poor quality air filters. If the air filter filtration effect is not good, will cause the air in the dust, sand and other impurities into the cylinder, the formation of abrasive wear. Therefore, the air filter needs to be replaced in time.

(7)The use of poor quality oil oil viscosity or level selection is not appropriate. Oil quality has a relatively large impact on the oil film, viscosity is too low will make it difficult to form the oil film, or the oil film is too thin will increase the wear of the piston. Or the use of poor quality oil: poor quality oil impurities, impurities in the piston and cylinder wall friction caused by cylinder pulling.

4. How to prevent engine cylinder failure?

Method 1
For a new engine or an engine after overhaul, it must go through break-in first. Under the condition of good lubrication, according to the principle of rotational speed from low to high, load from small to large. Remember not to drive violently.
Method 2
Choose a matching, correct oil label; at the same time, check the engine oil level height at the right time, add oil in time when there is a loss of oil; replace the oil according to the normal cycle.
Method 3
To strengthen the maintenance and inspection of the excavator cooling system, it is recommended to clean the cooling system and radiator and water tank regularly. Engine overheating can also cause internal parts to expand and contract thermally, potentially increasing wear and tear between parts as they expand.

3. Bearings (Crankshaft and Connecting Rod)

• Purpose: Bearings help reduce friction and wear between moving engine parts. Crankshaft bearings support the rotating crankshaft, while connecting rod bearings support the rods that transfer motion to the pistons.
• Included in the kit: Bearings for the crankshaft, connecting rods, and possibly the camshaft are included to ensure smooth engine operation and avoid premature wear.

4. Cylinder Liners or Sleeves

• Purpose: Cylinder liners are inserted into the engine block to provide a smooth, durable surface for the pistons to move against, helping to prevent wear and overheating.
• Included in the kit: New cylinder liners may be included in the kit to replace worn or damaged ones, ensuring the pistons can function properly within the cylinder.

5. Timing Belt or Chain

• Purpose: The timing belt or chain ensures that the engine’s camshaft and crankshaft work in perfect synchronization, controlling the timing of the opening and closing of the engine’s valves.
• Included in the kit: A new timing belt or chain is often included to ensure precise engine timing, which is crucial for optimal engine performance.

6. Valve Lifters, Push Rods, and Valve Springs

• Purpose: These components are involved in the operation of the engine’s valves, controlling the flow of air and fuel into the engine and the exhaust gases out.
• Included in the kit: Valve lifters (or tappets), push rods, and valve springs may be included to replace worn or damaged parts, helping maintain proper valve operation and preventing engine misfires.

7. Crankshaft and Camshaft (if required)

• Purpose: The crankshaft converts the piston’s linear motion into rotary motion, while the camshaft controls the opening and closing of the engine’s intake and exhaust valves.
• Included in the kit: Some overhaul kits may include a replacement crankshaft or camshaft if the original ones are worn or damaged. However, this is typically an optional part in a more extensive overhaul.

8. Oil Pump

• Purpose: The oil pump is responsible for circulating oil throughout the engine, ensuring that all parts remain lubricated and preventing excessive wear.
• Included in the kit: A new oil pump may be provided in the kit to ensure consistent oil pressure and effective lubrication of the engine after the overhaul.

9. Water Pump

• Purpose: The water pump circulates coolant throughout the engine to maintain optimal operating temperatures and prevent overheating.
• Included in the kit: Many overhaul kits include a new water pump to ensure that the cooling system remains efficient after the engine rebuild.

10. Timing Gears or Sprockets

• Purpose: Timing gears or sprockets connect the camshaft and crankshaft and help ensure the correct timing of the engine’s valve operations.
• Included in the kit: Timing gears or sprockets may be included to replace worn components and maintain the proper synchronization of engine parts.

11. Valve Seats and Guides

• Purpose: The valve seats and guides ensure that the engine’s valves open and close properly. The guides keep the valves aligned, and the seats provide a durable surface for the valves to seal against.
• Included in the kit: New valve seats and guides may be included to restore proper valve function, especially if the engine has seen a lot of wear.

12. Fuel Injectors (Optional)

• Purpose: Fuel injectors deliver the precise amount of fuel into the engine’s combustion chamber for optimal performance and efficiency.
• Included in the kit: Some overhaul kits will include new fuel injectors to replace old or clogged injectors, particularly if the engine has suffered fuel delivery issues.

13. Miscellaneous Parts

• Purpose: Other parts and components may also be included in a complete overhaul kit, such as washers, bolts, nuts, and other fasteners. These components help ensure that the rebuilt engine is properly assembled and sealed.
• Included in the kit: Miscellaneous items like O-rings, copper washers, and other small parts for reassembly may also be included.
