Water Injection and cooled exhaust gas recirculation (EGR) could be seen as competitive technologies: it has been demonstrated that at medium load a 40-50 % Water-to-Fuel Ratio (WFR) with Port Water Injection (PWI) has the same effect as an EGR-rate of 10%, which is seen as relatively limited even for petrol engines.

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.
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.
From the filters water was routed to the water injection pumps. The three water injection pumps each had a capacity of 221 m 3 /hr with a differential head of 2068.5 metres (209 bar). The pumps discharged to the 3,000 psi manifold and wellheads. The single water injection booster pump (221 m 3 /hr, 1,379 m (139 bar) differential head) took its ...
The General Electric/Allison J33 is an American centrifugal-flow jet engine, a development of the General Electric J31, enlarged to produce significantly greater thrust, starting at 4,000 lbf (18 kN) and ending at 4,600 lbf (20 kN) with an additional low-altitude boost to 5,400 lbf (24 kN) with water-alcohol injection.
Lean-burn gas engines are almost always turbocharged, resulting in high power and torque figures not achievable with stoichiometric engines due to high combustion temperatures. Heavy duty gas engines may employ precombustion chambers in the cylinder head. A lean gas and air mixture is first highly compressed in the main chamber by the piston.
Gas Engine for Electric Power Generation from INNIO Jenbacher Model of an S-type Hartop gas engine. A gas engine is an internal combustion engine that runs on a fuel gas (a gaseous fuel), such as coal gas, producer gas, biogas, landfill gas, natural gas or hydrogen. In the United Kingdom and British English-speaking countries, the term is ...
Gas turbines with DLE technology were developed to achieve lower emissions without using water or steam to reduce combustion temperature (Wet Low Emission (WLE) technology). [ 1 ] [ 2 ] WLE technology demands cleaning of large amounts of water, is heavy, takes more space and can be difficult to install offshore. [ 1 ]
