Diesel Engine Type

Basically, most marine engines use diesel engines. Below is a classification of diesel engine types based on cylinder placement.

Single Cylinder Diesel Engine.

Diesel engine type This is the simplest arrangement where all cylinders are in one line (in line) in parallel, as shown in Figure 12. This design is commonly used for diesel engines with up to 8 cylinders. Single-line diesel engines are usually equipped with vertical cylinders. However, the bus uses a diesel engine with a horizontal cylinder. Such diesel engines are basically vertical engines that tilt sideways to reduce weight.

Diesel Engine V. Adjustment

If a type diesel engine has more than eight cylinders, it is difficult to manufacture a rigid crankshaft and frame in a single chain arrangement. The –V arrangement (Figure 13a) has two connecting rods attached to each crankpin, allowing you to halve the length of the engine for a stiffer crankshaft. This is the most common arrangement of 8-16 cylinder diesel engines. A cylinder in a plane is called a bank. The angle A between the two banks varies between 30 and 120 degrees, and the most common angle A is between 40 and 70 degrees.

Radial Diesel Engine

Radial Diesel Engine Types All cylinders are located on one plane with the same centerline. Only one crank is fitted with all crankshafts. This type of diesel engine is made with 5, 7, 9 and 11 cylinders.

Flat Diesel Engine.

This type of diesel engine assembly is used for buses and trucks.

Multiple Diesel Engine Units.

The weight per horsepower, known as the specific weight of a diesel engine, increases with increasing size, bore, and stroke of the diesel engine. Two and four complete engines with 6 or 8 cylinders, respectively, by connecting each diesel engine to the main drive shafts (gb1 4a and b) in order to obtain a very high power engine without increasing the specific weight. Into one unit. Clutch and roller chain or clutch and gear help.

Reverse Piston Diesel Engine

Diesel engines with two pistons per cylinder driving the crankshaft are used in ships and railroads. This design demonstrates many benefits of fuel combustion, recoil time compensation, engine maintenance, and easy access.

Parts for diesel engine

When talking about diesel engine parts (diesel engine parts), understanding the operation or usage of various parts helps to fully understand the diesel engine as a whole. Each part or unit has a unique function that needs to be performed and works with other parts to form a diesel engine.

Diesel Engine Cylinder

At the heart of a diesel engine is a cylinder, where fuel is burned and electricity is produced. The inside of the cylinder of a diesel engine is formed by a liner or sleeve, and the diameter inside the cylinder is called the bore

Diesel Engine Cylinder Head

It includes a valve that closes one end of the cylinder, often introduces air and fuel, and exhausts exhaust fumes.

Diesel Engine Piston

The other end of the cylinder work chamber is closed by a piston, which transfers the fuel produced by combustion to the drive shaft. Diesel engine piston rings are lubricated with engine oil, creating an airtight seal between the piston and cylinder layer. Movement distance of the piston the end-to-end of the cylinder is called the stroke (hub).

Connecting Rod (Connecting Rod) Diesel Engine

One end, called the smaller end of the crankshaft, is attached to a gudgeon pin or gudgeon pin inside the piston. At the other end or the larger end there is a bearing for cranking. The crankshaft converts and converts the reciprocating motion of the piston during a power stroke into continuous rotation of the crankpin and vice versa during other strokes.
