The H27A is a modern version of the H25A, a reliable motor displacing 2.7 L (2,736 cc), coming from an 88 mm × 75 mm (3.46 in × 2.95 in) bore and stroke (VVT added in 2006). The engine is tuned to achieve most of its torque at low revs at the expense of raw power at high revs, making the engine very responsive in day-to-day driving.
A 36-volt lead–acid battery (housed in the vehicle's trunk and operating in a 42-volt electrical system) is used to operate a permanent magnet motor/generator unit mounted to the engine in a similar fashion to a conventional alternator. Then, through a high-tension drive belt, the motor/generator unit is capable of starting or assisting the ...
Chain tensioner on a single-speed bicycle Belt tensioner on a belt-drive bicycle Hydraulic bolt tensioner Hydraulic Puller-tensioner . A tensioner is a device that applies a force to create or maintain tension. The force may be applied parallel to, as in the case of a hydraulic bolt tensioner, or perpendicular to, as in the case of a spring ...
A long block engine replacement typically requires swapping out parts from the original engine to the long block. These parts can include the oil pan , timing cover , valve covers , intake manifold , emission-control parts, carburetor or fuel injection system, the exhaust manifold(s) , alternator , starter , power steering pump (if any), and ...
The 1962 Glas 1004 was the first mass-produced vehicle to use a timing belt. The 1966 Pontiac OHC Six engine was the first US mass-produced vehicle to use a timing belt, [21] [22] while the 1966 Fiat Twin Cam engine was the first mass-produced engine to use a timing belt with twin camshafts. Carmakers began to adopt timing belts in the 1970s ...
Alternator (silver) mounted on a V8 engine Alternator voltage regulator (brushes are worn out) An alternator is a type of electric generator used in modern automobiles to charge the battery and to power the electrical system when its engine is running. Until the 1960s, automobiles used DC dynamo generators with commutators.
The damper will be fitted at the front of the engine (opposite the clutch or transmission) just beyond the cover of the timing chain, gears, or belt, and behind the accessory drive pulley (which may carry one or more V, serpentine, or cogged belts.) In older vehicles the pulley and damper were separate units that were bolted together.
The fourth-generation Vitara features a 5-speed manual transmission for the 1.6-litre petrol engine and a 6-speed manual transmission for the 1.6-litre diesel engine. A 6-speed automatic transmission with paddle shifters is also available for the 1.6-litre petrol engine. [40] [41]
