Made of high-quality bearing steel, its mutual sliding cylindrical surface gap is only 0.001mm-0.0025mm.
It can be obtained through high-precision machining or grinding. Different fuel injectors are not interchangeable.
If the gap is too large, the injection pressure will drop and the spray quality will deteriorate. If the gap is too small, the needle valve will easily get stuck.

The clutch master cylinder collects pedal stroke information and uses the booster to separate the clutch.
When the driver steps on the clutch pedal, the push rod pushes the master cylinder piston to increase the oil pressure, and enters the clutch slave cylinder through the hose, forcing the clutch slave cylinder lever to push the release fork and push the release bearing forward

Brake chamber is the executive component in automotive air brake system, its function is to transform the pressure of compressed air to mechanical thrust that make brake camshaft rotating, make the vehicle do the braking action.
It consists of air inlet, cover, membrane, step disk, return spring, shell, push rod, clevis, clip and bolts, etc.

On July 18, 2020, CNHTC held an economic meeting for the first half of the year to find the gap and catch up with and win the tough battle in the third quarter.

Most of the current trucks basically use diesel engines with high thermal efficiency and high power.
Because trucks will encounter various road conditions while transporting goods, plus the reasons for their large transportation volume, the maintenance of their engines is of vital importance.

The clutch pressure plate is an important structure of the truck, which works together with the clutch disc and plays an important role in the safety of the truck.
The torque from the engine is transmitted to the clutch disc through the friction of the flywheel and the contact surface of the pressure plate with the clutch disc.

The crankshaft is the most important moving part in the engine. Its function is to form a crank connecting rod mechanism with the connecting rod.
The pressure generated by the combustion chamber drives the piston to move up and down

The turbocharger increases the intake air volume by compressing air. It uses the exhaust inertial impulse of the engine to push the turbine in the turbine chamber.
The engine speed increases, the exhaust gas exhaust speed and the turbine speed also increase synchronously, the turbine drives the impeller to compress more air into the cylinder.

Traffic mileage, we only need to consider whether we need to replace the brake pads when we drive 10,000 to 30,000 kilometers.
The front brake pads will be heavier than the rear brake pads under normal circumstances.
ou can check the front brakes when checking. The situation of the film. The specific number of kilometers traveled to replace the brake pads varies from person to person
