Italian manufacturer VM Motori has designed and built several different diesel engines for many third-party applications. Since 2013 Fiat and its successors own VM Motori and sell projects to automotive manufacturers including GM, Jeep, and other companies. VM Motori offers different range of engines depending on the applications: automotive, industrial, marine, and power generation.

Automotive applications

3 Cylinder

Script error: No such module "anchor".

R 315 SOHC

1.5 L (Template:Convert) I3, with a single overhead camshaft, four valves-per-cylinder, and common-rail direct fuel injection.

This engine was designed in 1998 with the related 4-cylinder variant R 420 SOHC. In 1999, VM granted Hyundai the license to manufacture both engines. Under terms of the agreement, Hyundai was able to manufacture the engines only to power its vehicles, while VM was free to grant other license agreements also in Korea, as happened in 2004 with GM Daewoo.[1][2]

Further evolutions were named RA 315 (Euro 4 compliant, up to Template:Convert ) and A 315 (Euro 5 compliant, up to Template:Convert ).

Applications:[3]

HR 392 SOHC

Template:Convert bore and stroke, Template:Convert straight-three engine, of an OHV pushrod design with two valves per cylinder. The block was cast iron, with an alloy head. It featured a four main bearing crankshaft, a balance shaft, and a Bosch VE3/10 fuel injection pump. A KKK 14 turbocharger was used, with an intercooler for the facelifted 'Nuova 33' of 1990.[4] Although out of production, this was the biggest three-cylinder engine ever made for a car.

Applications:

RA 325

Template:Convert Template:Convert at 4000 rpm Template:Convert 1900-2700 RPM.

4 Cylinder

RA 420 SOHC

Template:Convert straight-4, with four valves-per-cylinder and common-rail direct fuel injection. Produced by GM Korea and Hyundai Group (Hyundai and Kia).[7]

Applications:[8]

Script error: No such module "anchor".

HR 488 OHV

Template:Convert straight-4, with two (pushrod-actuated) valves-per-cylinder and indirect injection from Bosch (Spica in earlier versions). Template:Convert. This engine, developed for Alfa Romeo in 1979,[9] is also known as the VM80A and VM4 HT. Usually with KKK 16 turbochargers.

Applications:

Script error: No such module "anchor".

HR 492 OHV

Template:Convert straight-4, with two (pushrod-actuated) valves-per-cylinder and indirect fuel injection (Bosch VE 4/10, Spica in some earlier applications). Template:Convert. This engine is also known as the VM81A and VM4 HT 2.4. At first the 2.4 used KKK 24 turbochargers, later KKK 16s were installed for higher output.

Applications:

Script error: No such module "anchor".

425 OHV

Template:Convert straight-four, with two (pushrod-actuated) valves-per-cylinder and indirect fuel injection. Template:Convert, the engine size is variably referred to as either 2,500 or 2,499 cc. This engine too has been called HR 492, signifying four cylinders of Template:Convert bore. Timing gears, not belt.

Applications:

This engine was also used in some early Toyota Land Cruisers & Hilux, and Opel Fronteras.

The 425 OHV used in Chrysler Voyager 1991–2000 only 1996 and 1997 was with chain.

Between 1997 and 2001 this engine was manufactured at "Detroit Diesel Motores do Brasil" in Curitiba, Paraná, Brazil. The plant was eventually sold to Perkins after the Dodge Dakota stopped production locally.

R 425 OHV

425 OHV fitted with direct fuel injection for cleaner emissions.

Applications: Rover 800 late models circa 1998

R 425 DOHC

Template:Convert straight-4, with four valves-per-cylinder and common-rail direct fuel injection. Also available with variable geometry turbocharger (VGT) with upgraded power output of Template:Convert.[19]

Applications:

[20] power: Template:Convert at 4,000 rpm; torque: Template:Convert at 2,000 rpm

A derated version of this engine putting out Template:Convert was chosen in 2006 to power the new generation of the iconic London Taxi (the TX4).

R 428 DOHC (ENR)

R 425 DOHC enlarged to Template:Convert displacement.

Applications:

RA 428 DOHC

Evolution of R 428 DOHC. Base design for SDEC SC28R engine.

Applications:

A 428 DOHC

Evolution of R428 DOHC with Template:Convert common rail injection system and piezoelectric injectors

Applications:

R 754

The R 754 is a Template:Convert double overhead camshaft inline-four engine, featuring common-rail direct fuel injection and a fixed-geometry turbocharger. The bore and stroke are Template:Cvt. It produces between Template:Cvt. Fitted with an oxidation catalyst, particulate filter, and selective catalytic reduction, it meets the Euro 6 emissions standards and Stage V for off-road use.

Applications:

Schmidt Swingo 200+ (street sweeper)

Aebi TT241 / TT281 (Terratrac / Slope tractor)

Aebi TP420 (Multipurpose Transporter)

Aebi VT450 (Vario Transporter)

5 Cylinder

HR 588 OHV

Template:Convert inline-5, with two (pushrod-actuated) valves-per-cylinder and indirect fuel injection from either Bosch or Spica. Template:Convert. This engine is a five-cylinder version of the 2-litre HR488, and also uses KKK turbochargers.

Applications:

531 OHV

Essentially a 425 OHV with an extra cylinder. Template:Convert Straight-5, with two (pushrod-actuated) valves-per-cylinder and indirect fuel injection.

Applications:

R 531 OHV

531 OHV I5 engine, fitted with direct fuel injection.

Applications:

6 Cylinder

638 OHV

Essentially a 531 OHV with an extra cylinder. Template:Convert inline-six, with two (pushrod-actuated) valves-per-cylinder and indirect fuel injection.

Applications:

Also used by BMW Marine as a Template:Convert stern-drive package.

R 638 OHV

638 OHV fitted with direct fuel injection.

Applications:

D 642 OHV

Essentially an R 638 OHV enlarged to Template:Convert displacement. It was the first VM Motori engine to feature direct fuel injection.

Applications:

RA 629 DOHC

A planned Template:Convert double overhead camshaft V6 engine, featuring four valves-per-cylinder and common-rail direct fuel injection.

Developed for General Motors but stopped at the end of 2008; after Cadillac left the European market and Saab was put for sale, GM had no use for that engine.

RA629 (A29DT) applications (Europe)

A 630 DOHC

Template:Infobox automobile engine

A Template:Convert double overhead camshaft V6 engine, featuring four valves-per-cylinder and common-rail direct fuel injection. A variant complying with the emission norms of the North America market (NAFTA) is the L630 DOHC and marketed by Fiat Chrysler as the EcoDiesel. The high-performance, single turbo version is codenamed as A630 DOHC HP.[23]
