This invention relates to compositions and methods comprising lymphotoxin- receptor blocking agents, which block lymphotoxin- receptor signalling. The projection optics include a first lens group of negative refractive power that has at least one aspheric surface. The solenoids of the proportional apply and dump poppet valves are operated to control flow in or out of the brakes and modulate wheel pressure as required. Optionally, a polymeric dispersant, a non-volatile hydrocarbon carrier fluid and a solvent may be included for protecting and removing buildup of deposits on carburetor surfaces and intake valve system of a gasoline powered internal combustion engine.
