A trap primer (or trap seal primer) is a plumbing device or valve that adds water to traps.The water seals in traps are needed to prevent sewer gases from entering buildings, but because this water is exposed to the air, it is subject to evaporation over time in infrequently used floor drains, leading to the release of sewer gas into the environment.
The Ki-Gass system, also referred to as Kigass or K-Gas, is "a system of starting petrol and Diesel engines by injecting finely divided fuel in the form of a mist into the in-take pipe." [ 1 ] The system uses a hand-pump to spray fuel into the air in-take, thus priming the engine for easier starting.
Engines must be designed so that ignition conditions occur at the desired timing. To achieve dynamic operation, the control system must manage the conditions that induce combustion. Options include the compression ratio, inducted gas temperature, inducted gas pressure, fuel-air ratio, or quantity of retained or re-inducted exhaust.
A gas trap system involves "trapping" combustion gas as it leaves the muzzle. This gas impinges on a surface that converts the energy to motion that, in turn, cycles the action of the firearm. As the resulting motion is forward toward the muzzle of the gun, some sort of mechanical system is needed to translate this into the rearward motion ...
The technical requirements are outlined in Forest Service Specification FS5100-1. All spark arresters meeting the requirements of 36 CFR 261.52 must be certified and listed in the USDA Forest Service Spark Arrester Guide. This guide is a comprehensive directory of all qualified products available in the United States, and is published biannually.
A circa-1970 AMC 232 automotive engine. A petrol engine (gasoline engine in American and Canadian English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as E10 and E85).
In applications that use exhaust gas boilers, ammonium sulfate and ammonium bisulfate can accumulate on the boiler tubes, inhibiting steam output and increasing exhaust back-pressure. In marine applications, this can increase fresh water requirements as the boiler must be continuously washed to remove the deposits.
The engine was a steam engine converted to burn gaseous fuel and thus pushed in both directions. The fuel mixture was not compressed before ignition (a system invented in 1801 by Philippe LeBon who developed the use of illuminating gas to light Paris), and the engine was quiet but inefficient, [4] with a power stroke at each end of the cylinder ...
