AUTOMOBILE
ENGINE
An automobile engine is the internal combustion engine that powers a vehicle, converting
fuel into mechanical energy to move the vehicle. It is the heart of the vehicle, producing
power by burning fuel within its cylinders. There are different types of automobile engines,
such as:
Gasoline Engine: This is the most common type of engine found in cars. It operates on
gasoline or petrol as fuel and uses spark plugs to ignite the fuel-air mixture in the cylinders.
Diesel Engine: Diesel engines operate on diesel fuel, compressing the air in the cylinders
until it heats up enough to ignite the diesel fuel without spark plugs.
Electric Engine: Electric engines are becoming more popular in vehicles, running on
electricity stored in batteries. These engines are environmentally friendly and offer instant
torque for quick acceleration.
Hybrid Engine: Hybrid engines combine an internal combustion engine with an electric
motor. They can run on gasoline or electricity, switching between the two power sources for
better fuel efficiency.
Rotary Engine: Also known as a Wankel engine, this type of engine uses a rotary design
instead of pistons for combustion. It is compact and lightweight, often found in sports cars.
Turbine Engine: Turbine engines use a turbine to convert fuel into mechanical energy.
They are commonly used in aircraft but are not as common in automobiles.
These engines vary in efficiency, power output, and environmental impact, catering to
different needs and preferences of vehicle owners.

FUEL
SYSTEM
Car fuel system’s purpose is supply fuel from fuel tank to the engine cylinder. Also this
system provides the fuel storage and cleaning before admission to the cylinder.
The base fuel system has next main elements:
1. Fuel tank – it is a fuel storage reservoir. The fuel tank of modern cars is a difficult
system, which includes next elements: reservoir, fuel neck, fuel gauge, fuel pump, and
others;
2. Pipeline system – these is pipelines that provide fuel supply to other fuel elements;
3. Fuel pump – is a device which pumping the fuel from tank to the engine; Fuel pump of
modern injection systems creates enough high pressure. Electrical fuel pumps are
common using on the modern car. Diesel engine pumps can be two types of: low and
high pressure. Typically high pressure pump are used on the diesel engine.
4. Fuel filter (or filters). There are two types of fuel filters, like coarse fuel filter and fine
fuel filter; The purpose of filters are cleaning of fuel from different types of dirty, dusty
and so on.
5. Fuel injection device or Carburetor. It is device in which supply fuel and air to creating
air-fuel mixture.
Fuel injection device – are nozzles of the diesel or engine injector.But the fuel nozzles are
located into the head cylinder in diesel motors and direct fuel injector motors. And in
injector motors fuel nozzles are into intake manifold.
Fuel injection system construction. For the engine to run smoothly and efficiently, it
needs to be provided with the right quantity of fuel/air mixture according to its demands.
A fuel injection system consists of:
Fuel tank Fuel pump Fuel line
Fuel filter Fuel accumulator Fuel distributor
Inlet tract Inlet manifold Injectors
