The first Motorwagen used the Benz 954 cc (58.2 cu in) single-cylinder four-stroke engine with trembler coil ignition. [16] This new engine produced 500 watts (2 ⁄ 3 hp) at 250 rpm in the Patent-Motorwagen, although later tests by the University of Mannheim showed it to be capable of 670 W (0.9 hp) at 400 rpm. It was an extremely light engine ...
Today, this is known as "the first Marcus car" but would be better described as a cart. His second car, built and run in 1875 according to some sources, was the first gasoline-driven car and is housed at the Vienna Technical Museum. [30] [31] However, the latest research shows that it was not built until 1888/89. [32]
Animation of a two-stroke engine. A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston (one up and one down movement) in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle.
The Honda B20A engine series, known as the B20A and B21A, was an inline four-cylinder engine family from Honda introduced in 1985 in the second-generation Honda Prelude.Also available in the contemporary third-generation Honda Accord in the Japanese domestic market, along with the Accord-derived Vigor, the B20A was Honda's second line of multivalve DOHC inline four-cylinder engines behind the ...
The car weighed 850 lb (390 kg) and used Concord springs. [12] It had a top speed of 20 mph (32 km/h). [13] The car's success was partially by accident; in 1901, a fire destroyed a number of other prototypes before they could be approved for production, leaving the Curved Dash as the only one intact.
German firm Konig, who specialised in racing outboard motors, [6] built a few 1000cc H-8s in the 1970s, which were basically two of their VC500 flat fours mounted one above the other, with the direction of rotation reversed on one of them. Each half of the engine was a water cooled 2-stroke with rotating disc valve driven by a toothed belt via ...
Ole Evinrude formed Evinrude Outboard Motors, which he sold in 1913 in order to look after his sick wife. In 1919, Evinrude invented a more efficient and lighter two-cylinder motor. Having sold his part in Clemick & Evinrude, he founded ELTO or the Elto Outboard Motor Company. (ELTO was an acronym for "Evinrude Light Twin Outboard".)
[1]: 27 Wasted spark ignition system. A commonly used ignition system is wasted spark, [2] which is a simple ignition system using a double-ended coil firing both spark plugs on each revolution (i.e. during both the compression and exhaust strokes). This system is distributorless and requires only a single contact breaker and coil for the engine.
