The engine bore and stroke is 89 mm × 100 mm (3.50 in × 3.94 in) and a compression ratio ranging from 9.5:1 to 10.5:1 depending on the vehicle. [ 2 ] Output is rated 175 hp (130 kW; 177 PS) at 6000 rpm with 244 N⋅m (180 lb⋅ft) of torque at 4000 rpm in the Altima 2.5 and Sentra SE-R models.
The Power Drive 20 is part of a family of scalable electric motor designs produced by Yuneec. The Power Drive 20+ produces the same power but at a reduced rpm. [1] The family of engines is designed to use the company's own power controller, Lithium polymer battery pack and charger, as an integrated package of components. This ensures that all ...
The engine is a V-twin four-stroke, 895 cc (54.6 cu in) or 993 cc (60.6 cu in) displacement, fan-driven air-cooled, gasoline engine design. The larger displacement is achieved by increasing the stroke from 78 to 87 mm (3.1 to 3.4 in), but using the same bore of 86 mm (3.4 in).
Current Honda general-purpose engines are air-cooled 4-stroke gasoline engines but 2-stroke, Diesel, water-cooled engines were also manufactured in the past. The current engine range provide from 1 to 22 hp (0.7 to 16.5 kW ).
In 1990 Honda released 35 hp and 45 hp four-stroke models. They continued to lead in the development of four-stroke engines throughout the 1990s as US and European exhaust emissions regulations such as CARB (California Air Resources Board) led to the proliferation of four-stroke outboards. At first, North American manufacturers such as Mercury ...
The Ford Model T used a 177 cu in (2.9 L) sidevalve, reverse-flow cylinder head inline 4-cylinder engine. It was primarily a gasoline engine. It produced 20 hp (14.9 kW) for a top speed of 45 mph (72 km/h). It was built in-unit with the Model T's novel transmission (a planetary design), sharing the same lubricating oil.
Opposed-piston engines have been tried before in both 2 stroke and 4 stroke, the combination of the two different cycles is unique to this engine. The engine has a far greater efficiency over the break-even value known to combustion engines (about 35%) and closer to the one associated with steam turbines or electric engines (about 70%).
It is a four-stroke, vertical, water-cooled diesel engine. It is built around two cylinders (hence the "2" in 2GM20) of 75 mm in diameter and 72 mm in stroke, adding up to 0.635 litres in displacement: each cylinder is roughly the size and volume of a 300 ml soft-drink can.
