Five cylinder engine

The straight-five engine also referred to as an inline-five engine ; abbreviated I5 or L5 is a piston engine with five cylinders mounted in a straight line along the crankshaft, five cylinder engine. Five cylinder engine less common than straight-four engines and straight-six enginesstraight-five engines have occasionally been used by automobile manufacturers since the late s, particularly the Mercedes Benz's diesel engines from to and Audi's petrol engines from to the present.

Smaller and cheaper than a six, smoother and more powerful than a four. Or is it the performance of a four with the fuel economy of a six? The inline five-cylinder engine can be any of those things. Manufacturers from Acura to Volvo have experimented with this odd-numbered design—with varying degrees of success—since the Mercedes-Benz D. Always up for an engineering challenge, Honda dabbled in five-cylinder engines while studying how to build small jets. The G-series 2. Although these engines drove the front wheels, Honda mounted them longitudinally for more even weight distribution.

Five cylinder engines have managed to sneak themselves under the bonnets of some of the all-time greats in the realm of performance cars. Quite a roster. The four-stroke, five-cylinder setup leads to a firing interval of degrees of crankshaft rotation. In comparison to a four-cylinder engine which fires every degrees, there will be a 36 degree overlap, meaning another power stroke has occurred before the crankshaft rotates to the degree mark. This results in a power delivery is smooth, instead of the relative jolting action of an inline-four. The crankshaft journals are spaced out in a fashion to cater for the five cylinders. Relative to the first piston being at top dead centre, the second journal sits degrees counter-clockwise around the crankshaft, the third journal at degrees, the fourth at degrees and the fifth at 72 degrees or degrees from the origin. With the respective firing interval, this makes for a firing order of in most five-cylinder engines. This means the piston reciprocation hops from one side of the engine block to the other before finishing its full cycle with the central third piston. As with three-cylinder engines , the behaviour of the reciprocation due to the journal spacing and firing order leads to a balance of the vertical forces within the engine. Unfortunately, there is a torque imbalance along the horizontal plane of the engine, meaning a five-cylinder is constantly trying to twist or flip over its length.

Honda introduced a five-cylinder in with the Acura Vigor, though only stuck with the engine for around a decade.

In , the Audi 2. In , a turbocharged version was introduced, initially for the U. Several Volvo cars, from March to , were produced with Audi straight-five diesel engines, prior to the introduction of the Volvo D5 turbo-diesel engine; this engine was produced from to and was used in several diesel hybrid applications marketed as "twin engine" models. The first production straight-five petrol engine was the Audi 2. The final Volkswagen straight-five petrol engine was the Volkswagen EA 2. Contents move to sidebar hide. Article Talk.

Although less common than straight-four engines and straight-six engines , straight-five engines have occasionally been used by automobile manufacturers since the late s, particularly the Mercedes Benz's diesel engines from to and Audi's petrol engines from to the present. Straight-five engines are smoother running than straight-four engines and shorter than straight-six engines. However, achieving consistent fuelling across all cylinders was problematic prior to the adoption of fuel injection. Straight-five engines are typically shorter than straight-six engines , making them easier to fit transversely in an engine bay. Five-cylinder engines have a crankshaft with 72 degree angles.

Honda introduced a five-cylinder in with the Acura Vigor, though only stuck with the engine for around a decade. Oliver Bearman's Remarkable F1 Debut. Ferrari's V-6 Hybrid: Replacement for Displacement. The reincarnated pickups use a 2. Straight-five engines typically have a 72 degree crankshaft design. Audi even worked on a hp version of VW's EA four-cylinder , so it's not beyond its capability to do with four what it does with five. Since its introduction in , the passenger-car five-cylinder has always been an odd duck. Retrieved 24 August While Mercedes offered six-cylinder gas engines at the time, the company deemed a six-cylinder to be too costly and too heavy. Built for the Italian and German armed forces during World War II and later for civilian usage, the truck remained in production until Clifford Atiyeh is a reporter and photographer for Car and Driver , specializing in business, government, and litigation news.

This is why five-cylinders typically use a balance shaft. When using the typical firing order, primary forces—those created by pistons moving vertically—are perfectly balanced, as is the case with inline-four and -six cylinder engines. In comparison to a four-cylinder engine which fires every degrees, there will be a 36 degree overlap, meaning another power stroke has occurred before the crankshaft rotates to the degree mark. Archived from the original on 6 December Watch Next. In fact, it lived on into the Ford era. Our little Ford Ranger pickup departed in , but the rest of the world was treated to an all-new Ranger, and with it came a new engine option, the 3. Packaging—where stuff goes—defines everything. Contents move to sidebar hide. By , the JTD five added 10 more valves and a new Multijet system that injected diesel five times during each combustion cycle, instead of two, to make the engines run quieter and smoother. Ford also notably borrowed the Volvo five-cylinder while it owned the Swedish brand for its second-generation Focus ST and RS, with its strongest showing in the RS, where the 2. In recent years the engine has been falling out of favour, with Volvo announcing in it would discontinue building them, for example.
