That will make life difficult. However, All of the air that flows into the intake goes into a combustion chamber eventually. So you have to get the right amount of fuel into all of the air? You cannot just squirt stuff in occasionally. Which is where 'continous stream' comes in Obviously as the injector is only an on/off valve you would have your Pulse width modulation and hope pulses of fuel are disturbed enough by the throttle butterfly to even them out. >I've been trying to confirm if Rover use the same principle as GM, ie. >asynchronous injection - no answer yet.... I understand the general what most of the different sensors do as it is fairly easy to convert from Carb to FI if you understand what each sensor is doing. However I can only do this for the stuff that works in a similar way to carbs.. stuff like asyncronous injection is a little beyond me at the moment. could someone explain or is there a site that explains these somewhere? FWIW the rover mini system is a MEMS system... what ever that means.

I know >for a fact that some outboard marine engine controllers do this. Outboard engines are FI???? Wow!! Things have changed in the past 5 years. Why would they do this? Manufacturers are still putting ECUs in the engine bay of cars. This is a pretty nasty place for electronics. I can see the reason for putting FI in cars as it improves fuel ecconomy and power along with controling the fuel so that it doesn't clog the CAT. But why on a small outboard engine? Surely you would want to keep the thing as simple as possible using NO electronics as Sea water isn't electronics freindly by any means. Coments?

Flap doors are obviously a huge restriction. Hot wire and film sensors seem like a good method, but MAPs are TOTALLY unobtrusive on the intake system. I've noticed that the majority of American cars use MAP sensors, as well as newer Hondas. European manufacturers seem to favor the film or wire sensor. Is it an economic issue, like the American resistance to ditch pushrods? ------------------------------ Date: Mon, 11 Oct 1999 20:19:22 -0400 From: rr Subject: Re: DIY_EFI Digest V4 #572 > ---------------------------------------------------------------------- > > Date: Mon, 11 Oct 1999 00:50:01 +1000 > From: Phil Lamovie > Subject: Re:Up Up and Away > > > > There is absolutely no need to calculate the mass of the atmosphere on > Earth and then divide that by the ratio of volume of inlet manifold. > Though it would work. > > Please note the total lack of Patents for Altitude correction of > aircraft fuel injection computers.
