    Why can't an internal combustion engine self-start from zero rpm without being spun-up by a starter?

    As Waross said about the Model T, a similar thing could be done with 1930s Rolls-Royce models. https://www.motorsportmagazine.com/archive/article/may-1975/48/starting-rolls-royce Bill

    Brushless permanent magnet motor troubleshooting

    Thanks for that it smoked, however, it's the mechanical arrangement of the windings that I'm trying to get a grip on. I'll have a trawl through the Texas docs to see whether there are any references. I've been there before but it was a while ago. Bill

    Brushless permanent magnet motor troubleshooting

    I think I am asking benta this question --- Are there any good sources you could recommend for teaching myself the electrical basics of brushless motors? I'm basically a mech eng, and partly (very partly) educated in electrical, so other readers - please don't shoot me for not knowing. I'm...

    What is offline assembly in car engine assembly line?

    "Off line" can also refer to sub-assemblies assembled on a smaller line, independent of a main assembly line, which are fed to the mainline via a small buffer store. Fuel tanks are a good example - tank, neck, fuel pump, some fuel lines, tank straps etc. assembled on the parallel line and fed...

    Increased fuel pressure: any benefit on port injected engine

    You would be attending to the fuel maps in the ECU too, I assume, if you increase the fuel pressure? Bill

    Generic question on longevity of modern automotive engines at high load

    Well, Brian, I'm not painting them all, just recounting conversations I've had with FMC devt engrs here in Europe re the 1.0L engine. Bill

    Generic question on longevity of modern automotive engines at high load

    MikeHalloran - your reference to the Ford Ecoboost engine/s is right on the ball. Through industry links, I have heard that some aspects of the cooling system have been designed without much thought to manufacturing processes and the rate of degradation of the cooling system internals (casting...

    Electric potential - Aluminum Steel Interface

    Look up the Galvanic Series to see how the potentials vary between the metals that are actually in contact and not the steel that has been plated. Try this link and look at page 24...

    Are there in-tank ethanol/gasoline ratio sensors?

    I'm pretty sure that the old AC Rochester company had a dielectric sensor back in the 80's Bill

    Additional heating unit - for extremely cold countries

    Traditionally, Scandinavian countries would use electric block heaters (like an electric kettle element, fitted via the casting core plug holes) to keep the engine/coolant up to a temperature that would make starting easier, after a vehicle was shut down overnight. Sometimes, if a block heater...

    throttle body

    On some 'modern' diesels, a throttle device is used to help control the ratio of clean air to EGR. Bill

    [Im]balance of inline four cylinder engines

    No engine temperature guage on new UK Fords

    First - john66b - are you in the UK? If you are, then I'm not surprised at your experience with FMC 'Technical' help. Much of that function has gone out to a contract house (MSX, I think) and they regularly advertise for people to do the job. I think they just work from a script. dgallup -...

    No engine temperature guage on new UK Fords

    Trouble is, you are all looking at the issue from the point of view of engineers, enthusiasts and people who give a s??t. This accounts for less than 20% of the buyers, I would guess, according to Pareto. The rest are more interested in what colour the radio display is, in terms of...
