After a virtual disappearance from motor racing and automotive engineering for nearly 50 years, a small company known as VerMot AG of Grafschaft, Rhineland [3] planned to revive the Veritas name. It produced a concept known as the Veritas RS III in 2001, [ 4 ] initially using a BMW sourced 6.0 litre V-12, producing 670 hp (500 kW; 679 PS). [ 5 ]
This is most likely to occur on a carbureted engine in cold weather, after a running engine has been shut off briefly before being restarted. Doing so can cause the choke valve to configure the mixture for a cold engine start, despite higher actual temperatures, resulting in an overly rich mixture and flooded engine.
Carburetor heat uses hot air drawn from the heat exchanger or heat stove (a metal plate around the exhaust manifold) to raise the temperature in the venturi section high enough to prevent or remove any ice build-up. Because hot air is less dense than cold air, engine power will drop when carburetor heat is used.
A cold start can be difficult for an engine due to higher viscosity of oil and fuel in cold temperatures. Generally speaking, diesel engines have more difficulty starting at low outside temperatures than gasoline engines, and electric engines have the most problems. Diesel engines do not use spark plugs to ignite the air fuel mixture and rely ...
Nitrogen, oxygen and hydrogen are the most encountered gases in cases of gas porosity. [6] In aluminium castings, hydrogen is the only gas that dissolves in significant quantity, which can result in hydrogen gas porosity. [9] For casting that are a few kilograms in weight the pores are usually 0.01 to 0.5 mm (0.0004 to 0.02 in) in size.
During the testing of a car, one of the pipe plugs backed out. In order to get back on the road, one of the Welch brothers installed a press-fit quarter or half dollar coin into the hole using a hammer. The design of the Welch plug was refined based on this principle of a press-fit metallic disc. [8]
A small Snow Peak portable stove running on MSR gas and the stove's carrying case The parts of portable gas stove—gas cartridge, burner and regulator. A portable stove is a cooking stove specially designed to be portable and lightweight, used in camping, picnicking, backpacking, or other use in remote locations where an easily transportable means of cooking or heating is needed.
Most gas ranges and cooktops use sparking devices to ignite the burner flame. This eliminates the need for a pilot flame , which wastes energy. Most of these sparking device-equipped ranges require the user to control the ignition sparking manually, resulting in a three-step process required to operate the burner:
