Carbon dioxide cleaning was contemplated in the 1930s, and the "pellet" approach was developed in the 1970s by E.E. Rice, C.H. Franklin, and C.C. Wong. [4]: 276 The introduction of CO 2 snow cleaning, with its ability to remove sub-micron-scale particles, is credited to Stuart Hoenig of the University of Arizona , who first published on the ...
Carbon build-up in the intake manifold will occur when blow-by gases are allowed to permanently contaminate the intake air because of a failing PCV system. [12] Carbon build-up or oil sludge from blow-by gases on intake valves are usually not a problem in port injected engines. This is due to the fact that the fuel hits the intake valves on the ...
For other vehicles, he and another source said that periodic use of a concentrated engine cleaner every 100,000 miles will "often" clean out carbon buildup. [25] However, journalist and automotive mechanics instructor Jim Kerr says that with some brands of gasoline, deposits can build up on intake valves in less than 10,000 kilometers (6200 ...
The vapors which are displaced from the fuel tank by the incoming fuel are routed via the vapor vent line to the canister and are absorbed by activated carbon. These canisters are made of either steel or plastic. The size of this canister is tailored to accommodate expected evaporative emissions.
In internal combustion engines, water injection, also known as anti-detonant injection (ADI), can spray water into the incoming air or fuel-air mixture, or directly into the combustion chamber to cool certain parts of the induction system where "hot points" could produce premature ignition.
The largest part of most combustion gas is nitrogen (N 2), water vapor (H 2 O) (except with pure-carbon fuels), and carbon dioxide (CO 2) (except for fuels without carbon); these are not toxic or noxious (although water vapor and carbon dioxide are greenhouse gases that contribute to climate change).

An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing.
