Engine balance refers to how the inertial forces produced by moving parts in an internal combustion engine or steam engine are neutralised with counterweights and balance shafts, to prevent unpleasant and potentially damaging vibration. The strongest inertial forces occur at crankshaft speed (first-order forces) and balance is mandatory, while ...
Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.
The Mitsubishi 4B1 engine is a range of all-alloy straight-4 piston engines built at Mitsubishi 's Japanese "World Engine" powertrain plant in Shiga on the basis of the Global Engine Manufacturing Alliance (GEMA). [1][2][3] Although the basic designs of the various engines are the same, their exact specifications are individually tailored for ...
The first person to build a working four-stroke engine, a stationary engine using a coal gas-air mixture for fuel (a gas engine), was German engineer Nicolaus Otto. [4] This is why the four-stroke principle today is commonly known as the Otto cycle and four-stroke engines using spark plugs often are called Otto engines.
A straight-four engine (also referred to as an inline-four engine) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The majority of automotive four-cylinder engines use a straight-four layout [1]: pp. 13–16 (with the exceptions of the flat-four engines produced by Subaru and Porsche) [2] and ...
Two-stroke diesels with high pressure forced induction, particularly turbocharging, make up a large percentage of the very largest diesel engines. In North America, diesel engines are primarily used in large trucks, where the low-stress, high-efficiency cycle leads to much longer engine life and lower operational costs. These advantages also ...
Catalytic converter (on N9C/N9E/NSD/NSE/N9D) The Ford I4 DOHC engine is a cast iron block 4-cylinder inline internal combustion engine with twin overhead camshafts, produced by the Ford Motor Company at Dagenham Engine Plant. It was initially available as a 2.0 litre 8-valve version, and later in 2.0 and 2.3 litre 16-valve versions from 1989 to ...
Thermodynamics. In engineering, the Miller cycle is a thermodynamic cycle used in a type of internal combustion engine. The Miller cycle was patented by Ralph Miller, an American engineer, U.S. patent 2,817,322 dated Dec 24, 1957. The engine may be two- or four-stroke and may be run on diesel fuel, gases, or dual fuel. [1]
