best oil for Renault The necessary high voltage
The necessary high voltage, typically 10,000 volts, is supplied by an induction coil or transformer. The induction coil is a fly-back system, using interruption of electrical primary system current through some type of synchronized interrupter. The interrupter can be either contact points or a power transistor. The problem with this type of ignition is that as RPM increases the available of electrical energy decreases. This is especially as problem since the amount of energy needed to ignite a more dense fuel mixture is higher. The result was often a high rpm misfire.
Capacitor discharge ignition was developed. It produces a rising voltage that is sent to the spark plug. CD system voltages can reach 60,000 volts.19 CD ignitions use step-up transformers. The step-up transformer uses energy stored in a capacitance to generate electric spark. With either system, a mechanical or electrical control system provides a carefully timed high-voltage to the proper cylinder. This spark, via the spark plug, ignites the air-fuel mixture in the engine's cylinders.
While gasoline internal combustion engines are much easier to start in cold weather than diesel engines, they can still have cold weather starting problems under extreme conditions. For years the solution was to park the car in heated areas. In some parts of the world the oil was actually drained and heated over night and returned to the engine for cold starts. In the early 1950s the gasoline Gasifier unit was developed, where, on cold weather starts, raw gasoline was diverted to the unit where part of the fuel was burned causing the other part to become a hot vapor sent directly to the intake valve manifold. This unit was quite popular until electric engine block heaters became standard on gasoline engines sold in cold climates.20

There are several possible ways
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:

How to take care of the paint?
Among the drivers are very popular preparations, which produce no doubt brilliance of automotive paint. Interestingly, many of these measures not only contains polishing agents, but also agents responsible for applying a protective coating on our car. Thanks to such treatment as pasting of the car, so we can not only improve the aesthetics of the car, but also the fact that the car paint will be preserved. This, in turn, it will be more durable and resistant not only to mechanical damage, but also resistant to corrosion and other adverse to paint processes. Concern for the car paint is so profitable, because we can thereby postpone the need for removal of rust and so on.
