Fixing a Cracked Diesel Injector

Fixing a Cracked Diesel Injector   Refurbishing a diesel injector often requires repairing or replacing a cracked injector. In order to fix a cracked diesel injector, mechanics need masking tape, a marker, a set of wrenches, rags, welding equipment, a pressurized hose, injector cleaning equipment, and protective eye equipment.   Step Materials Needed Diesel Injector Repair Instructions […]

Diesel Engine: How A 4 Stroke Diesel Engine OR Compression Ignition Cycle Works?

Diesel Engine: How A 4 Stroke Diesel Engine OR Compression Ignition Cycle Works? Diesel Engine Principle and Working Cycle Explained: Basically, there are two types of diesel engine types – the Four Stroke and Two Stroke. The ‘Diesel Cycle’ uses higher Compression-Ratio. It was named after German engineer Rudolph Diesel, who invented and developed first Four-Stroke diesel engine. The […]

How does Engine Valve Timing help?

How does Engine Valve Timing help? This air-fuel mixture (also known as charge) has both mass and motion. The entire charge cannot enter the cylinder even when the piston reaches the end of its downward stroke because the opening of the inlet valve is small. Therefore, the pressure in the combustion chamber remains below the atmospheric pressure, […]

Valve Timing: What Is It And How It Affects The Engine Performance?

Valve Timing: What Is It And How It Affects The Engine Performance? Engine Valve Timing Explained Firstly, read here about how the engine valves open & close. The engine valves are just like the nose. An automotive engine uses valves for it’s ‘breathing’ (inhale/exhale) process. The engine’s camshaft opens and closes the valves at a specific interval. The timing […]

What is a Unit Injector?

What is a Unit Injector? Furthermore, fuel injection systems on the CRDi diesel engines use ‘Unit-Injector’ or the ‘Pump/Injector’. It merges the functions of an injector-nozzle and the injection pump into a single unit. This design consists of an individual pump assigned to each cylinder rather than a common pump used for all cylinders in earlier generation […]

Needle Valve Stuck In Nozzle

As we know,nozzle is one vital precision component in diesel engine.Its quality could affect the engine performance a lot.But we can offer experienced that the needle valve is stuck inside the nozzle.Today diesel injection specialist will tell you the reasons and solutions. Why the need valve stuck? 1.The anti-rust oil is not cleaned when replacing […]
