The mechanical fly-weight governors of inline and distributor diesel fuel injection pumps used to control fuel delivery in diesel engines under a variety of engine loads and conditions could no longer deal with the ever-increasing demands for efficiency, emission control, power and fuel consumption. These demands are now primarily fulfilled by ...
Engines with manifold injection, and an electronic engine control unit are often referred to as engines with electronic fuel injection (EFI). Typically, EFI engines have an engine map built into discrete electronic components, such as read-only memory. This is both more reliable and more precise than a three-dimensional cam.
The first four-stroke direct-injection petrol engine for a passenger car was released the following year, in the Mercedes-Benz 300SL sports car. [41] However the engine suffered lubrication problems due to petrol diluting the engine oil, [42] [43] and subsequent Mercedes-Benz engines switched to a manifold injection design. Likewise, most ...
The Ford EEC (Electronic Engine Control) system, which utilized the Toshiba TLCS-12 microprocessor, went into mass production in 1975. [ 7 ] The first Bosch engine management system was the Motronic 1.0 , which was introduced in the 1979 BMW 7 Series (E23) [ 8 ] This system was based on the existing Bosch Jetronic fuel injection system, to ...
It performs the same function as a conventional unit injector in an internal combustion engine, such as in an on-road or off-road vehicle or a diesel-electric locomotive. The pressurized delivery of fuel is camshaft -driven, but the timing of the injector's internal operations are controlled by the engine control unit so as to achieve certain ...
Engine controls demand one of the highest real-time deadlines, as the engine itself is a very fast and complex part of the automobile. Of all the electronics in any car, the computing power of the engine control unit is the highest, typically a 32-bit processor. [citation needed] A modern car may have up to 100 ECU's and a commercial vehicle up ...
The two groups must work together to save the lodge owned by the soldiers' former commander. Rotten Tomatoes Score: 77%. Why you should watch it: Critics said "White Christmas" is warm and cozy ...
He revealed details of his prototype engine early in 1912, [39] and the design was further developed by the large scale engine builder F. E. Baker Ltd during 1912 [40] and the results displayed on their stand at the Olympia Motor Cycle show in November 1912. The engine was a high compression four-stroke motorcycle engine, with the gasoline fuel ...
