The Rotax 916 iS is an Austrian piston aircraft engine, ... Fuel type: gasoline minimum MON 85, RON 95, AKI 91, leaded or unleaded, avgas 100LL, maximum ethanol 10%;
The Rotax 915 iS is a four-cylinder four-stroke, horizontally-opposed, turbocharged, air and liquid-cooled, gasoline engine design, with a mechanical gearbox reduction drive. The turbocharger has a compression ratio of 3.5:1 and the engine will have a critical altitude of 15,000 ft (4,572 m).
The Ikarus C42 is a single-engined high-wing monoplane with side-by-side seats for two in a 1.22 m (48 in) wide cabin. The C42 is manufactured with either an 80 hp (60 kW) Rotax 912 engine or a 100 hp (75 kW) Rotax 912s engine. The Rotax engine has a low fuel consumption and relatively low noise.
The transferred fuel was lost through the fractured fuel line, which was leaking at about 13 tonnes per hour (more than 3.6 kg/s). This caused a higher-than-normal fuel flow through the fuel-oil heat exchanger, which in turn led to a drop in oil temperature and a rise in oil pressure for the no. 2 engine. [3] [8]
The cockpit width is 1.15 m (45 in). Standard engines available are the 100 hp (75 kW) Rotax 912ULS, the Rotax 912iS [5] and the 115 hp (86 kW) Rotax 914 four-stroke powerplants. A glider towhook is optional equipment. [2] [3] [6] The design has been developed into a three to four seat aircraft, the Aerospool WT10 Advantic. [2]
Four-stroking is a condition of two-stroke engines where combustion occurs every four strokes or more, rather than every two. Though normal in some instances at idle, extremely high engine speeds, and when letting off the throttle, such firing is uneven, noisy and may, in cases of malfunction, damage the engine if allowed to continue unabated.
The fuel consumption per mile or per kilometre is a more appropriate comparison for aircraft that travel at very different speeds. [citation needed] There also exists power-specific fuel consumption, which equals the thrust-specific fuel consumption divided by speed. It can have units of pounds per hour per horsepower.
Consumption map of a 1.5-litre three-cylinder diesel engineA consumption map or efficiency map [1] is a chart that displays the brake-specific fuel consumption of an internal combustion engine at a given rotational speed and mean effective pressure, in grams per kilowatt-hour (g/kWh).
