The Volvo Modular Engine is a family of straight-four, straight-five, and straight-six automobile piston engines that was produced by Volvo Cars in Skövde, [15] Sweden from 1990 [16] until 2016. All engines feature an aluminium engine block and aluminium cylinder head, forged steel connecting rods, aluminium pistons and double overhead camshafts.
Sight-glass lubricator. A needle valve adjusts the rate of flow, which may be seen as drops passing through the window beneath the glass reservoir.. A total-loss oiling system is an engine lubrication system whereby oil is introduced into the engine and then either burned or ejected overboard.
Volvo nearly completed the phaseout in 2016 [47] with only two variants of the five-cylinder diesel remaining in production for the 60-series models. In December 2014, Volvo introduced the first hybrid variant of a VEA engine with the launch of the XC90 T8. It uses an electric rear axle drive (ERAD) for both electric propulsion and AWD ...
Aside from the increased bore size, the engine is identical to the B21. Volvo used a slightly different mold for the turbo engines to cast a boss for the turbo oil return line. Because a turbocharged engine has a higher operating temperature they used sodium filled exhaust valves and a thermostat controlled oil cooler (air/oil model).
With the early development of cars and the almost universal rear-wheel drive layout, the final drive (i.e. rear axle) ratio for fast cars was chosen to give the ratio for maximum speed. The gearbox was designed so that, for efficiency, the fastest ratio would be a "direct-drive" or "straight-through" 1:1 ratio, avoiding frictional losses in the ...
Particles in the oil can also cause serious problems with oil pressure. After oil flows through the engine, it returns to the oil pan, and can carry along a lot of debris. The debris can cause problems with the oil pickup screen and the oil pump itself. The holes in the oil pickup screen measure about 0.04 square inches (0.26 cm 2). [6]
Volvo designed the SI6 [3] ("short inline 6") straight-six automobile engine for use in 2007 models. An evolution of the company's long-used straight-five Volvo Modular engine, which itself is an evolution of the Volvo B6304 straight-six engine, the SI6 can be mounted transversely for front wheel drive or all wheel drive applications. Despite ...
This engine was the first to locate one balance shaft higher than the other, to counteract the second order rolling couple (i.e. about the crankshaft axis) due to the torque exerted by the inertia caused by increases and decreases in engine speed. [6] [7] In a flat-four engine, the forces are cancelled out by the pistons moving in opposite ...
