Volvo Cars has a long reputation for comfort, solidity, safety and longevity. Its loyalty has historically been high and as a maker of reliable inline car engines. Volvo Car Corporation is part of the FoMoCo PAG along side Jaguar and Land Rover of Britain. All Volvo car engines can be bought here at both new and used, reconditioned or secondhand, and are 100% guaranteed.

When Volvo started in 1927 they ordered the engines from the engine manufacturer Penta in Skövde. The first engine was the four cylinder side valve 28 hp Type DA.

The present owner Ford Motor Company has allowed Volvo to continue to design their own engines, with a new-generation straight-6 introduced in 2006.

Volvo Naming

Volvo has used three systems to name their engines:
1955–1985 — four or five characters
1985–1994 — five or six characters
1993–1994 — six to eight characters

Generally, the following naming scheme is used:
B for Bensin (gasoline/petrol) or D for Diesel
Two digits for engine displacement (moved after number of cylinders from 1993)
One for valves per cylinder (not found before 1985)
One to three characters for engine features

Volvo OHV Engine

It was an OHV straight-6. It was a simple pushrod engine with a cast iron block. The EB, EC, and ED were straight-6 engines with four main bearings and displacing 3.7 L (3670 cc/223 in³) and producing 80 to 90 hp (60 to 67 kW). These engines were used in the PV series.

Volvo B4B Engine

Volvo’s second engine design after the OHV engine of the 1930s and 1940s was the straight-4 B4B of 1944 and its descendants, the B14A and B16. These were cast iron pushrod engines like their predecessor, and used just three main bearings.

Volvo B18 Engine

This B30 was a straight-6 automobile engine produced by Volvo Cars starting in 1969, and used in the company’s 164 sedan from 1969 through 1975. It was also used in the Volvo C303 military vehicle. Other uses included marine, industrial and agricultural applications. It was a robust pushrod engine and displaced 3.0 L (2978 cc/181 in³).

Output ranged from 130 hp (97 kW) with the B30A equipped with two Zenith-Stromberg 175CD2SE sidedraught CD carburetors to 160 hp (119 kW) (SAE net) from the higher-compression B30E equipped with Bosch D-Jetronic electronic fuel injection. The engine offered smooth running and high levels of torque at low engine speeds.

Volvo V6 Engine

Volvo introduced the PRV engine, its only V6 in 1974. The PRV was available in 2.7 and 2.8 L configurations, with SOHC heads. The PRV was developed together with Renault and Peugeot, thus the name PRV.

Volvo DOHC Engine

Overhead camshaft (OHC) valvetrain configurations place the camshaft within the cylinder heads, above the combustion chambers, and drive the valves or lifters directly instead of using pushrods. When compared directly with pushrod (or I-Head) systems with the same number of valves, the reciprocating components of the OHC system are fewer and in total will have less mass.

Though the system that drives the cams may become more complex, most engine manufacturers easily accept the added complexity in trade for better engine performance and greater design flexibility. The OHC system can be driven using the same methods as an I-Head system, these methods may include using a timing belt, chain, or in less common cases, gears.

Many OHC engines today employ Variable Valve Timing and multiple valves to improve efficiency and power. OHC also inherently allows for greater engine speeds over comparable cam-in-block designs.
There are two overhead camshaft layouts:
Single overhead camshaft (SOHC)
Double overhead camshafts (DOHC)

Volvo Modular Engine

Volvo began a line of modular engines in 1990, with straight-4, straight-5, and straight-6 variants developed with the help of Porsche.

Volvo T5 engine

T5 is a name used by Volvo for high performance, turbocharged, 2.3 and 2.4 litre 5 Cylinder internal combustion engines manufactured, initially for use only in Volvo vehicles, but which eventually was used more widely.

The currently manufactured engine is around 2.4 litres. It has 5 cylinders and a double overhead cam valvetrain, is fitted with an intercooled turbocharger and is transversely mounted. The engine ‘red lines’ at 6500rpm.

Volvo Super 6 Engine

Ford’s Volvo Cars subsidiary designed the SI6 (“short inline 6”) straight-6 automobile engine for use in 2006 models.

An evolution of the company’s long-used straight-5, which itself is an evolution of the Volvo B6304 straight six engine, the SI6 can be mounted transversely for front wheel drive applications or longitudinally for rear wheel drive. Despite the added cylinder and displacement, the engine remains compact, and is in fact 1 mm shorter than the previous straight-5.

The engine will be offered in two displacements initially — a 3.0 L turbocharged version and a 3.2 L naturally aspirated version. Both will offer variable cam timing, though only the turbo version varies both the intake and exhaust valves.

Volvo V8 Engine

A V8 engine is a V engine with eight cylinders.
