    MTBE concerns

    This may not be very high on consideration but the smell is enough to make many people sick. Also there are people that are easily driven into serious Bronchial problems from the vapors. I know this first hand. N.J. made MTBE manditory and PA. tried it some years ago. Now neither uses it...

    Hydrogen Injection

    If it is of any help, Ford has two of their engines in limited production using hydrogen injection. A v6 for airport equipment and there v10 for E 450 BUS application. I believe they may be the first to get to this level.

    Clean Emissions = Higher Operating Temp ??

    Ford's new 3 valve 5.4L DOHC engines use variable exhaust cam timing. The future says that they will go to the control of both intake and exhaust cams with an effort to increase power over a wider band and use cam timing/phasing change to get rid of the present EGR method by taking advantage...

    ECU/PCM or Tranny Problem ? 95 Ford Explorer

    I can't help you on the new unit you have a lead on but, I do think besides the wear in the valve body bores, the valve body and all the SSs are exposed when the pan is removed. If you are going to keep the vehicle another 5 years, I think another trans is in order or have yours rebuilt so the...

    Low BTU Fuel

    Very well said by Hemi. The fuel is the final determinant of were you end up with any combination by it's limits of detonation vs load. This limit is of course determined by CR, intake temp, chamber design, timing, fuel and other parameters. Getting as many of these finalized is the key...

    Bosch Common Rail Controller

    From what I know about how hardware is controlled, you need not only a very flexible hardware driver but software written for signal processing inputs from sensors to arrive at the end control results versus load, speed and all the operating stratigy needs. A good place to get some idea of how...

    ECU/PCM or Tranny Problem ? 95 Ford Explorer

    Here is what your dealing with on a 5R55E transmission. The trans has a turbine sensor. The actual gear ratio can be computed anytime the trans is not shifting properly. An actual gear ratio is computed in each gear and compaired to the predicted gear ratio in order to determine the actual gear...

    Engine efficiency maps

    I think the best load maps are those that are done by auto makers who use Speed Density engine control systems. They have to run the engine under every possible load situation the user might encounter; build the programming, sensor input and output controlling hardware to work over the whole...

    Fuel Injection, What pump to use?

    We need to know what kind of pump system you now have. In general, the fuel system will be rated in L/HR as you have stated. My knowlwge of FI is that you need a hi pressure pump sized to deliver enough fuel at the injector working pressure and ECM derived max. pulse width in the (90% range) to...

    old gasoline

    The oil mix for 2 cycle is a precision deal for hi performance such as Kart racing. To much and the engine goes lean and sticks a piston from excess heat. Remember that the oil is metered though the carb in most engines along with the gas. Too little oil and the piston still sticks fast from...

    old gasoline

    I'm not at all an expert on gas formulation, but over the long term and school of learning, I do know that that gas is a formulation science that varied per refiner, time of year and area of distribution. Gas formulation is composed of a number of different chemicals in addition to base stock...

    spark plugs

    One of the greatest attributes of LPG is it's clean burning. The combustion chambers are always very clean and crankcase oil contamination is generally very low. This leads to another interesting question about lube oil specs that may not have to meet certain requirements that gasolene imposes...

    IR vs. OPEN PLENUM INTAKE RUNNERS

    The use to which you are putting the engine would be considered for the type of inlet tract used. The IR setup uses a carb with different airflow capacity than a plenum type, with the signal so strong that the carb sees airflow signal in both directios such that the carb will meter fuel in the...

    Air Tank Boosting for Dire Traffic Situations

    I just saw a mag advertisement on just such a bottle compressed unit supplying a turbo.

    Time Advance Processor for LPG(Propane)

    I am Ford savvy and here is the deal for the way the Knock sensor is used. A check of all the EFI truck and car models since 1985 to about 94 for 5L and 5.7L engines shows this sensor is used only on the light trucks. Why; because it is a protection for the engine from low rpm heavy loading...
