Types of Automotive Engines

Automotive engines are mainly heat engines or electric engines. The heat engines are classified into internal and external combustion engines or steam engines. Most of the engines are piston or internal and external combustion engines. They are also divided into four-cycle engines and two-cycle engines then by means of working process such as fuel ignition they are divided into gasoline engines, carburetor engines and diesel engines The fuel used in automotive engines can be varied into petrol, diesel, gasoline, Hydrogen etc.

The operating cycles of various types of engines are the same or similar to that of carburetor engines. In case of diesel engines, high pressure of the diesel fuel is sprayed through the tip of the nozzle which is pumped directly to the cylinder, then it is finally mixed with air. Automotive engines are also distinguished by the placement and number of cylinders. Based on it they are classified into in-line engines, V-engines, flat engines, rotary engines etc. Then they are classified on the basis of value location present in the cylinder head or block, cylinder capacity, motor cooling system, function, and so on. In recent times the four-cycles over headed valve and liquid-cooled carburetor-types of piston engines are used in cars and medium and small sized trucks

Diesel Engines.

Diesels are the very low cost fuel which burns cheaper than gasoline and other types of fuels. They also have certain advantages over carburetor type of engines in case of fuel consumption and service length, this type of engine is used mainly for propulsion of heavier trucks and larger buses. Gasoline engines are superior because of their design, lower cost production, power, good starting, and its control over exhaust smoke, but in case of modern higher speed diesel engines has certain properties which makes them come closer towards carburetor engines, the diesel engines nowadays has begun to find applications in various types of automotives. The view of diesel engine is given below.


Straight or inline Engines

This type of engines has cylinders arranged one after another in a straight line. These engines  are considerably easy to build. They also have ultimately low production cost and maintenance cost. They are also very light in weight hence they are mostly preferred in front wheel drive cars. They are extremely fuel efficient than v type engines. The view of straight or inline engine is given below.


V-Type Engines

The V-type engines have two sets of cylinders which are placed in 90 degree. It has various advantages such as shorter length, greater rigidity, heavier crankshaft, and low attractive profile. This type of engines has wide applications in sport vehicles mainly in formula1 cars.


Boxer or flat engines

Flat engines are another one of the type of engine which has minimum center of gravity than other type of engines, the vehicles which are using this type of engines has certain benefits such as better or good stability and control. These type of engines are wider thus it is difficult to install it in front engine cars.
