G60 refers to an inline-four cylinder automobile petrol engine, which uses a specific method of forced induction - by way of a specific type of supercharger. The G60 engine was formerly manufactured by the German carmaker Volkswagen Group, and was installed in a limited number and range of 'hot hatch' cars from their Volkswagen Passenger Cars marque from August 1988 to July 1993.〔ETKA〕 A smaller G40 engine of identical design had earlier been installed in the Mk2 Volkswagen Polo GT G40 from August 1986 to July 1994. ==Design and specifications== The G60 is a 1.8-litre internal combustion engine, which displaces from a cylinder bore of , and a piston stroke of . 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 at 5,800 revolutions per minute (rpm), and could generate a turning force torque of at 4,000 rpm. Although it was based on an existing Volkswagen Group engine from their EA111 series, it underwent so many modifications, it is usually regarded as a separate powerplant from others which the Group produced. It was named after the intricate "G-Lader" magnesium-cased supercharger that it was mated to - this supercharger having a diameter inlet, hence the "G60" moniker. It utilised 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 the earlier, smaller version, called the G40 1.3-litre engine. This displaced from a bore of , and a stroke of . The G40s supercharger had an inlet diameter of , hence the "G40" name. This G40 engine produced a maximum power of at 5,500 rpm, and torque of at 3,500 rpm. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Volkswagen G60 engine」の詳細全文を読む スポンサード リンク
