What determines car insurance?

As you know, every car owner is obliged to insure your car. The fee, which you need to bring in this respect, however, is dependent on many factors. First of all, a key criterion in this regard is the model and brand of the insured car. This is the value of the car depends on the amount of possible compensation. It is also important that in which he was made our car and how many kilometers is already on the meter. It is known that with the number of kilometers traveled risk of defects is increasing. Nevertheless, important in this regard is how old is the owner of the car, because the amount of insurance premium depends on the metric of the holder of the car.


In 2-stroke crankcase scavenged engines

In 2-stroke crankcase scavenged engines, the interior of the crankcase, and therefore the crankshaft, connecting rod and bottom of the pistons are sprayed by the 2-stroke oil in the air-fuel-oil mixture which is then burned along with the fuel. The valve train may be contained in a compartment flooded with lubricant so that no oil pump is required.

In a splash lubrication system no oil pump is used. Instead the crankshaft dips into the oil in the sump and due to its high speed, it splashes the crankshaft, connecting rods and bottom of the pistons. The connecting rod big end caps may have an attached scoop to enhance this effect. The valve train may also be sealed in a flooded compartment, or open to the crankshaft in a way that it receives splashed oil and allows it to drain back to the sump. Splash lubrication is common for small 4-stroke engines.

In a forced (also called pressurized) lubrication system, lubrication is accomplished in a closed loop which carries motor oil to the surfaces serviced by the system and then returns the oil to a reservoir. The auxiliary equipment of an engine is typically not serviced by this loop; for instance, an alternator may use ball bearings sealed with its lubricant. The reservoir for the oil is usually the sump, and when this is the case, it is called a wet sump system. When there is a different oil reservoir the crankcase still catches it, but it is continuously drained by a dedicated pump; this is called a dry sump system.

Reciprocating

Classification

There are several possible ways to classify internal combustion engines.

Reciprocating:

By number of strokes

Two-stroke engine

Clerk Cycle 1879 6
Day Cycle

Four-stroke engine (Otto cycle)
Six-stroke engine

By type of ignition

Compression-ignition engine
Spark-ignition engine (commonly found as gasoline engines)

By mechanical/thermodynamical cycle (these 2 cycles do not encompass all reciprocating engines, and are infrequently used):

Atkinson cycle
Miller cycle

Rotary:

Wankel engine

Continuous combustion:

Gas turbine
Jet engine

Rocket engine
Ramjet

The following jet engine types are also gas turbines types:

Turbojet
Turbofan
Turboprop
