A spark-ignition engine with direct fuel injection is a type of piston combustion engine that, unlike a spark engine with single-point or multi-point fuel injection or carburetor method of mixture preparation, does not burn only a homogeneous mixture.

Fuel is injected directly into the cylinder during the intake or compression stroke using the injection valves, atomizing and vaporizing it before the spark plug ignites the mixture with a spark.

Diesel or petrol? This topic will never get old as long as these types of engines stay in cars. Every day when one opens a car forum, one encounters questions like - diesel or petrol, petrol vs. diesel, diesel vs. petrol, and our favorite one is: Is diesel or petrol better?

Of course, these topics are very popular, and many users decide to give advice or at least highlight the advantages of one and the other type of engine. However, a short discussion is always followed by an exchange of opinions and stormy communication with a lot of swearing and insults, which ends with sentences that diesel…

A petrol engine is a piston combustion engine that burns gasoline and converts thermal energy into mechanical work.

This article will shed light on the petrol engine and its function and advantages over the diesel engine.

This article will shed light on petrol and diesel engines and focus on how they work and their advantages and disadvantages.

Without further ado, let's take a look at both of these engines.

The throttle valve controls the air supply to the engine. It is used by gasoline engines but also by some modern diesel engines. The throttle valve is located in the intake system and is mechanically or electronically connected to the gas pedal.

When the gas pedal is pressed, the throttle valve opens. In the case of a mechanical control system, the damper reacts immediately. In contrast, the electronic control is the responsibility of the ECU (Engine Control Unit), which controls the throttle valve based on the position of the gas pedal.

Spark plugs are an essential part of any gasoline engine. Without these small devices, the gasoline engine could not work, so every car owner with this type of engine should know more about them.

Spark plugs are electrical devices located in the head of each cylinder. The spark plug ignites a compressed mixture of fuel and air in the cylinder using an electric spark. Unlike a glow plug, a spark plug works continuously.
