I laughed at that too but decided to leave it alone. :) |

Yep, had a '72 duster that required 3 pumps of the pedal to get going. Come to think of it, the 454 in my boat requires 2 pumps of the throttle before it will start too..yes its "carburetor injected" ;) |

you ---daisies---... ;D So what exactly do you call it? Throttle body injection? Or do you just leave the "injection" part off. Technically, the air/fuel mixture is still "injected" into the cylinders, just not under pressure. |

i think you are confusing a few different things here. first you have carburettor, which relies on a drop of pressure created by the downstroke of the piston to create a vuccu... vaaccu (christ how DO you spell it?) a suction. the resulting flow of air past the venturi causes fuel to be drawn into the airstream where it is vaporised. then there is single point fuel injection. this is where there is one injector (or more perhaps) that are positioned on the throttle body. the injector pretty much replaces the venturi in this case. then there is multi point fuel injection. generally ther will be one injector per cylinder positioned near the inlet valve. so when the valve opens the injector is sending its charge virtually straight into the cylinder. note that NONE of these methods are injecting directly into the cylinder. this naturally is called DIRECT INJECTION and is commonly used in diesel engines. the charge is injected directly into the cylinder just as the cylinder has compressed the iar as faar as it can go. this causes the deisel to ignite (no spark plug). direct injection is much more costly and technical because of the extreme pressure the system has to work at. which is one of the reasons a deisel engine is quite expensive. incidentally more than one hapless mechanic has met his demise while testing deisel injectors because he got hit by a high pressure spray of deisel, going straight into the blood stream... |

oh, and i think some of you guys missed the point about what i was saying. us folk with old cars are imune from this new type of theft not because they dont want the car, but because there are no fancy gadgets to rip out. this is the pajero for example. the car was exactly where the owner had left it overnight! |
