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.

Life without the automotive industry - is it even possible?
Nowadays it is difficult to imagine life without the automotive industry. Public transportation, private cars and buses at the end of the truck the goods to any kind of shops are an integral part of our everyday life. Moving cars is very comfortable, so it's no surprise that it has now become almost necessary to lead a comfortable life element. Settlement of the simplest things in a quick way, or even trips on shorter routes are really enjoyable when you have your own car or motorcycle. For many people, the same drive various means of transport is a very nice feeling. Moreover, the use of buses or cars is sometimes necessary. Carrying heavy goods they are most often carried out also by means of heavy equipment moving on the roads.
Basic knowledge - Public costs
The external costs of automobiles, as similarly other economic externalities, are the measurable costs for other parties except the car proprietor, such costs not being taken into account when the proprietor opts to drive their car. According to the Harvard University,11 the main externalities of driving are local and global pollution, oil dependence, traffic congestion and traffic accidents; while according to a meta-study conducted by the Delft University12 these externalities are congestion and scarcity costs, accident costs, air pollution costs, noise costs, climate change costs, costs for nature and landscape, costs for water pollution, costs for soil pollution and costs of energy dependency. The existence of the car allows on-demand travel, given, that the necessary infrastructure is in place. This infrastructure represents a monetary cost, but also cost in terms of common assets that are difficult to represent monetarily, such as land use and air pollution.
