Volkswagen G60 engine
Template:Short description Template:Use British English Script error: No such module "Unsubst". Template:Infobox automobile engine
The Volkswagen G60 and G40 are inline–four-cylinder car petrol engines, which use forced induction by way of a scroll-type supercharger. The G60 engine was manufactured by the German automaker Volkswagen Group and used in a number of their hot hatch cars from August 1988 to July 1993.[1]
The smaller G40 engine of identical design was previously installed in the Mk2 Volkswagen Polo GT G40 from August 1986 to July 1994.
Design and specifications
The G60 is a Script error: No such module "convert". internal combustion engine, from a cylinder bore of Script error: No such module "convert"., and a piston stroke of Script error: No such module "convert".. Its cylinder block is constructed from grey cast iron, and its cylinder head is cast aluminium alloy, with additional post-production heat treatment. The crankcase contains a forged steel crankshaft which runs in five main bearings, and cast pistons with increased size gudgeon pins. It has two valves per cylinder (eight valves in total), which are operated by a toothed belt-driven forged steel single overhead camshaft (SOHC) via hydraulic valve lifters, with the valves being closed by two concentric valve springs. Charged air is cooled via an intercooler, and the operation and control of the engine, is managed by a Bosch Digifant engine control unit, which includes common rail electronic multi-point fuel injection and a knock sensor. It produced a maximum rated motive power output of Script error: No such module "convert". at 5,800 rpm, and could generate a turning force torque of Script error: No such module "convert". at 4,000 rpm.
Although based on an existing Volkswagen Group engine from their EA827 series, it underwent so many modifications that it is usually regarded as a separate powerplant from others which the group produced. It was named after the "G-Lader" magnesium-cased supercharger that it was mated to - this supercharger had a Script error: No such module "convert". diameter inlet, hence the "G60" moniker.[2] It utilized a side-mounted intercooler (SMIC), positioned in front of the left front wheel, to lower the temperature of the compressed charged engine intake air.
The G60 engine was developed from an earlier, smaller version called the G40 based on their EA111 series. This engine displaced Script error: No such module "convert". from a bore of Script error: No such module "convert". and a stroke of Script error: No such module "convert".. The G40's supercharger had an inlet diameter of Script error: No such module "convert"., hence the "G40" name. The engine produced a maximum power of Script error: No such module "convert". at 5,500 rpm, and torque of Script error: No such module "convert". at 3,500 rpm.
Applications
The original G40 was used in the Mk2 Volkswagen Polo Coupé GT G40. The G40 engine could propel it to a top speed of Script error: No such module "convert"..
The larger G60 engine debuted in August 1988 in the B3 Volkswagen Passat G60 saloon, and the Mk2 Volkswagen Golf G60 hatchback. In the Golf G60, it was capable of propelling the car from a standstill to Script error: No such module "convert". in 7.8 seconds, reaching a top speed of Script error: No such module "convert"..
A month later, in September 1988, the Volkswagen Corrado G60 was released. Performance figures for the Corrado G60 state a 0 - Script error: No such module "convert". time of 8.3 seconds and a top speed of Script error: No such module "convert"..
In the United States, the G60 engine was used only in the Corrado, and this was dropped in 1992 in favour of the newer, more powerful VR6 engine.
A limited-production, four-wheel drive Syncro variant of the Golf G60, called the Golf Rallye was also powered by the eight-valve G60, but the engine was reduced to Script error: No such module "convert". for sports homologation purposes. It included a larger intercooler which is mounted across the full width of the radiator. Power remained at Script error: No such module "convert"..
A 16-valve G60 engine was used in the ultra-rare Golf Limited, of which only 71 were produced by VW Motorsport, all with four-wheel drive.[3][4] Power was raised to Script error: No such module "convert"., and the car could now accelerate from 0 - Script error: No such module "convert". in 6.4 seconds, reaching a top speed of Script error: No such module "convert"..
The G60 engine, like any supercharged or turbocharged engine, was sensitive to high air temperatures, so engine performance very much depended on the weather conditions. Some models, like the Golf Rallye, or even some variants of the Golf G60, had a bigger, better-placed intercooler, resulting in increased, and more consistent performance compared to the standard placed intercooler.
Technologies found in the G40 and G60 engines have subsequently been used in other Volkswagen engines.[5] They first used this technology with turbochargers in their Turbodiesel 'TD' engines. This evolved into their Turbocharged Direct Injection 'TDI' diesel engines.
VW engine ID codes
All Volkswagen G-Lader internal combustion engines are inline four-cylinder SOHC designs, operate on the four-stroke cycle petrol engines with Bosch Digifant electronic multi-point fuel injection, are water-cooled, and use a G-Lader supercharger:
