Four-stroke engine

The four-stroke engine, the device and the principle of operation.

The four-stroke engine was first demonstrated by Nicolaus Otto in 1876 and is therefore also known as the Otto cycle. The technically correct term is a four-cycle cycle. The four-stroke engine is the most common type of engine at present. They are installed on almost all cars and trucks.

The four-stroke engine was first demonstrated by Nicolaus Otto in 1876 by motors and therefore it is also known as the Otto cycle. auto mechanic Four-stroke engine The technically correct term is a four-stroke motorcycle cycle engine. A four-stroke engine may be the most common type of engine in advance of the present. They installed motor motor vases on all mekanik cars and trucks.

The four-stroke engine consists of cylinders mounted on the crankcase and closed at the top with a head. From below to the sump is attached a pallet. In the cylinder head, an internal combustion engine is installed. Internal combustion engine valves - car intake and exhaust engines - and spark plugs (in petrol) or injectors for a gasolina car fuel injection component. Engine operating principle diesel engine (in diesel engines). Inside the cylinder, the piston is reciprocatingly moved, which is connected via a piston pin to the upper connecting rod head. car structure The lower end of the connecting rod covers the engine of the crankshaft engine of the crankshaft neck, the cervical neck of which is the train parts and the engine of the car gazolina engine machine is fitted with the engine 3d on bearings in the engine crankcase. The piston is sealed in the cylinder by means of piston rings. The flywheel is fixed to the end of the crankshaft. The position of the 2106 engine that takes the gearbox of the piston in how the engine works is the end of its stroke upward, called the top engine of the auto dead center (TDC), and the position of the mechanic engine is the engine repair at the end of the stroke down the engine - the machine is the lower dead center (BDC). Moving the piston from one dead point to the diesel engine is a two-stroke engine the other when the engine is running is called a tact. The volume that is generated above the asynchronous mechanical box of the engine by the piston motors of the machines when it is in the TDC is called the volume of the combustion chamber. The volume that frees the piston when it moves from TDC to BDC is called the displacement or engine displacement. The sum of the volume of the combustion chamber and the working volume is called the total volume of the cylinder.
