The Quad 4 is the first domestic regular production DOHC four-cylinder engine wholly designed and built by GM, the only similar prior example being the Chevrolet Cosworth Vega, whose DOHC head was designed by Cosworth in England. In addition to the 2.3-liter DOHC Quad 4s, there was also a short-lived 2.3-liter SOHC variant called the "Quad OHC ...

A Universal Atomic 4, installed in a C&C 29 Mark 1 sailboat. The Universal Atomic 4 is a four-cylinder, gasoline engine produced by the Universal Motor Company between 1949 [1] and 1984 for use as auxiliary power on sailboats. [2] Both 18 horsepower (13 kW) and 30 horsepower (22 kW) versions of the engine were produced. [3]
Thru the late 1980s, the classic 13 ft 4 in (4.06 m) Whaler, and the 16 ft 7 in (5.05 m) Montauk were the most popular models in terms of sales. Gradually though the company moved away from these designs to a more conventional deep-vee hull, and after 1996 no more of the classic tri-hull boats were manufactured.
The boat has a draft of 3.50 ft (1.07 m) with the standard fin keel and is normally fitted with a small 2 to 4 hp (1 to 3 kW) outboard motor for docking and maneuvering. [1] [3] The design has sleeping accommodation for two people, with a double "V"-berth in the bow cabin.
Dual ignition provides two advantages: redundancy in the event of in-flight failure of one ignition system; and more efficient burning of the fuel-air mixture within the combustion chamber. [ 1 ] [ 2 ] In aircraft and gasoline-powered fire fighting equipment, redundancy is the prime consideration, but in other vehicles the main targets are ...
A catenary pole of the system. Catenary wires and contact wires are tensioned by individual tension balancers. The basic system unit is an elementary electrical section consisting of a segment of one or more parallel tracks, each with a contiguous contact (or catenary or trolley) wire for the locomotive pantograph and an electrically separate feed wire.
Accelerate-by-wire or throttle-by-wire, [17] more commonly known as electronic throttle control, is a system that actuates vehicle propulsion without any mechanical connections, such as cables, from the accelerator pedal to the throttle valve of the engine or other propulsion systems. In electric vehicles, this system controls the electric ...
