The richer fuel mixture was needed to address an engine stalling problem, resulting in emissions of up to 10 grams per mile of carbon monoxide (CO), nearly three times the limit of 3.4 g/mi. While the EPA and Justice Department contended that GM intentionally violated emissions standards, GM said that was "a matter of interpretation."
For Exhaust gas recirculation (EGR) equipped engines, the intake manifold temperature must be greater than or equal to 86-100 degrees Fahrenheit, depending upon intake manifold pressure. For EGR-equipped engines, the engine coolant temperature must be greater than or equal to 125-140 degrees Fahrenheit, depending on intake manifold pressure.
On 22 August 2006, after being re-fitted with 750 brake horsepower (560 kW) 'LSR' versions of the JCB444 engines, [2] the JCB Dieselmax car broke the official FIA diesel engine land speed record, attaining a speed of 328.767 mph (529.099 km/h). 24 hours later the JCB Dieselmax car broke its own record, achieving a speed of 350.092 mph (563.418 ...
Weigh-in-motion or weighing-in-motion (WIM) devices are designed to capture and record the axle weights and gross vehicle weights as vehicles drive over a measurement site. . Unlike static scales, WIM systems are capable of measuring vehicles traveling at a reduced or normal traffic speed and do not require the vehicle to come to a st
The maximum RPM of an engine is limited to the airflow through the engine, the displacement of the engine, the mass and balance of the rotating parts, along with the bore and stroke of the pistons. [4] Formula One engines can rev up to 15,000 rpm as per Formula One rules [5] because of their smaller displacement, low mass, and short stroke.
One line of thought is the motor was an evolution of either of the HRN8 marine diesel, or the HRP8 stationary diesel. [1] The engines used Crossley's system of exhaust pulse pressure charging and developed 1,200 horsepower (895 kW) at 625 rpm, though in 1981 they were down-rated to 875 hp at 600 rpm. There were no valves, and inlet and exhaust ...
This engine was the first to locate one balance shaft higher than the other, to counteract the second order rolling couple (i.e. about the crankshaft axis) due to the torque exerted by the inertia caused by increases and decreases in engine speed. [6] [7] In a flat-four engine, the forces are cancelled out by the pistons moving in opposite ...
The Wärtsilä RT-flex96C is a two-stroke turbocharged low-speed diesel engine designed by the Finnish manufacturer Wärtsilä. It is designed for large container ships that run on heavy fuel oil . Its largest 14-cylinder version is 13.5 meters high, 26.59 meters long, weighs over 2,300 tonnes , and produces 80.08 megawatts .
