Straight-4
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 (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power st ...

Austin-Healey 100
The Austin-Healey 100 is a sports car that was built by Austin-Healey from 1953 until 1956. Based on Austin A90 Atlantic mechanicals, it was developed by Donald Healey from his Nash-Healey 2 door sports car, which had Nash mechanicals instead, to be produced in-house by his small Healey car company in Warwick. Healey had Tickford build a single Healey Hundred for the 1952 London Motor Show, and the design impressed Leonard Lord, managing director of Austin, who was looking for a replacement for the unsuccessful A90. Body styling was by Gerry Coker, the chassis was designed by Barry Bilbie with longitudinal members and cross bracing producing a comparatively stiff structure upon which to mount the body, innovatively welding the front bulkhead to the frame for additional strength. In order to keep the overall vehicle height low the rear axle was underslung, the chassis frame passing under the rear axle assembly. Lord struck a deal with Healey to build it in quantity; bodies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Mitsubishi 4M4 Engine
The Mitsubishi 4M4 engine is a range of four-cylinder diesel piston engines from Mitsubishi Motors, first introduced in the second generation of their Montero/Pajero/Shogun SUVs. They superseded the previous '' 4D5'' engine family, main differences are enlarged displacements and the utilization of one or two over-head camshafts. Originally available only as a 2835 cc intercooled turbo, detail improvements in 1996 and a larger 3.2 litre option in 1999 served to improve power, torque, fuel economy and emissions. The final version has 3.0 litres swept volume and Common rail direct injection. 4M40 Inline 4-cylinder SOHC, bore x stroke = , , swirl combustion chamber Naturally aspirated Compression ratio 21.0:1, Zexel Distributor type injection pump, at 4000 rpm, at 2000 rpm Applications: * 1996–1999 Canter (lightest-duty), , at 2000 rpm Intercooled turbo gen 1 Compression ratio 21.0:1, at 4000 rpm, at 2000 rpm Applicat ...

Citroën DS
The Citroën DS () is a Front-mid-engine, front-wheel-drive layout, front mid-engined, front-wheel drive executive car manufactured and marketed by Citroën from 1955 to 1975, in fastback/sedan, wagon/estate, and convertible body configurations, across three series of one generation. Marketed with a less expensive variant, the Citroën ID, the DS was known for its aerodynamic, futuristic body design; unorthodox, quirky, and innovative technology, and set new standards in ride quality, car handling, handling, and braking, thanks to both being the first mass production car equipped with hydropneumatic suspension, as well as disc brakes. The 1967 series 3 also introduced ''directional headlights'' to a mass-produced car.After this feature was first introduced on the 1948 Tucker 'Torpedo', of which 50 were built. Italian sculptor and industrial designer Flaminio Bertoni and the French aeronautical engineer André Lefèbvre styled and engineered the car, and Paul Magès developed th ...

Engine Movingparts
An engine or motor is a machine designed to convert one or more forms of energy into motion (physics), mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. Geothermal energy, geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form; thus heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a ...

Balance Shaft
Balance shafts are used in piston engines to reduce vibration by cancelling out unbalanced dynamic forces. The counter balance shafts have eccentric weights and rotate in the opposite direction to each other, which generates a net vertical force. The balance shaft was invented and patented by British engineer Frederick W. Lanchester in 1907. It is most commonly used in inline-four and V6 engines used in automobiles and motorcycles. Overview The operating principle of a balance shaft system is that two shafts carrying identical eccentric weights rotate in opposite directions at twice the engine speed. The phasing of the shafts is such that the centrifugal forces produced by the weights cancel the vertical second-order forces (at twice the engine RPM) produced by the engine. The horizontal forces produced by the balance shafts are equal and opposite, and so cancel each other. The balance shafts do not reduce the vibrations experienced by the crankshaft.
