Young people, often breaching the rules of the road are in fact for insurers customers not profitable and that is why they use this kind of preventive measures, such as increasing fees for insurance with every accident.
Five-stroke engine In 1879, Nikolaus Otto manufactured and sold a double expansion engine (the double and triple expansion principles had ample usage in steam engines), with two small cylinders at both sides of a low-pressure larger cylinder, where a second expansion of exhaust stroke gas took place; the owner returned it, alleging poor performance.
In 1906, the concept was incorporated in a car built by EHV (Eisenhuth Horseless Vehicle Company) CT, USA;22 and in the 21st century Ilmor designed and successfully tested a 5-stroke double expansion internal combustion engine, with high power output and low SFC (Specific Fuel Consumption).23 Six-stroke engine The six-stroke engine was invented in 1883.Four kinds of six-stroke use a regular piston in a regular cylinder (Griffin six-stroke, Bajulaz six-stroke, Velozeta six-stroke and Crower six-stroke), firing every three crankshaft revolutions. The systems capture the wasted heat of the four-stroke Otto cycle with an injection of air or water. The Beare Head and "piston charger" engines operate as opposed-piston engines, two pistons in a single cylinder, firing every two revolutions rather more like a regular four-stroke.Źródło: https://en.wikipedia.org/wiki/Internal_combustion_engine
However, not always the cheapest solution turns out to be the best for driver or car owner.
For example, if you want to consider the option of supplying gas in our car, we must know that it is necessary to install proper installation.
This is connected with considerable costs, but on the other hand, avoids the higher fees in the future.
