The BAC One-Eleven airliner also used water injection for its Rolls-Royce Spey turbofan engines. Filling the tanks with jet fuel instead of water led to the Paninternational Flight 112 crash. [7] In 1978, Olympic Airways Flight 411 had to abort and return to its take-off airport due to a failure of the water injection system or its processes. [8]
The water injection system injects water into the primary or secondary fuel nozzle inputs, usually on natural gas fired engines. The GE LM6000 PC is rated to provide more than 43 MW with a thermal efficiency of around 42% LHV [ 1 ] at ISO conditions .
The LMS100 PA gas turbines utilize water injection for NOx control. The LMS100 PB gas turbine uses dry low NOx (DLE) combustors. The LMS100 PB gas turbine uses dry low NOx (DLE) combustors. The first LMS100 PB unit entered commercial operation in 2013.
A gas engine differs from a petrol engine in the way the fuel and air are mixed. A petrol engine uses a carburetor or fuel injection. but a gas engine often uses a simple venturi system to introduce gas into the air flow. Early gas engines used a three-valve system, with separate inlet valves for air and gas.
In 1959, important orders for the engine were the Boeing 707-120B and Boeing 720B when American Airlines ordered one 707 powered by JT3D turbofans and KLM ordered a JT3D-powered Douglas DC-8. Earlier 707s and DC-8s had been powered by the JT3C and JT4A turbojets, and the improved efficiency of the turbofan soon attracted the airlines.
Snowmaster 824 QXE Single-Stage Gas Snowblower. The Toro Snowmaster 824 QXE stands apart from other single-stage gas snowblowers because of its intuitive controls and powerful engine.
Engines with electronic fuel injection have sensors that compensate for the cold by pumping more gasoline into the mixture. The engine continues to run rich in this way until it heats up to about ...
This system works very well in getting rid of crankcase vapors which are harmful to the engine. As per the earlier engines, the road draught tube system also created pollution and objectionable odors. [1] The draught tube could become clogged with snow or ice, in which case crankcase pressure would build and cause oil leaks and gasket failure. [2]
