It features variable compression ratio (variable valve timing) with brake thermal fuel efficiency over 42%; high power density (approx.
The 22T and 24TS engine have many potential military and commercial applications; it would make an excellent diesel electric hybrid.
4-cylinder, 4-valve all aluminum direct injected turbo/supercharged diesel engine.
Leo-Diesel 69T and Leo-Diesel 71TS T he 69T and 71TS are high power density diesel engines based on the COTS GM LS Series production truck and high performance (638 HP) gasoline engine.
What the PDFs allow us to say
requires it, such as for hybrid powertrains or if you want to represent the axle performance with powertrain test results.
You may alternatively test the powertrain with a chassis dynamometer if you measure speed and torque at the powertrain's output shaft or wheel hubs.
(2) For testing hybrid engines, connect the engine's crankshaft directly to the dynamometer and measure torque at that location.
Cool the powertrain during testing so temperatures for oil, coolant, block, head, transmission, battery, and power electronics are within the manufacturer's expected ranges for normal operation.
You may use electronic control module outputs to comply with this paragraph (c).
Establish a baseline matrix of engine operating conditions as defined by rack setting and engine speed.
Document engine performance as well as exhaust emissions at these conditions for certified No.
Develop and install instrumentation to provide information regarding injection timing, ignition delay, pressure, rate of pres8ure rise, and knock intensity for baseline and alcohol operation.
At each 2400 RPM test condition, fumigate various proofs of ethanol and methanol as limited by engine knock or misfire.
Obtain for each operating condition, performance data including thermal efficiency and power output as well as regulated emissions data (CO, HC, NO ).
