During my career I have seen many examples of holed pistons due to insipient detonation as opposed to the short lived temporary transient form brought about by being in the wrong gear,poor batch of fuel from the supermarket etc.The range of effects from good old fashioned detonation/knocking can...
It is important to note that manufacturers are there to make profit for their shareholders not to speculate in technology for the sake of it. If something has benefits that are worthwhile eg cheaper,lighter,faster etc then they will rise to the pile and be selected for production.
If something...
I had thought that this one was already done to death,detonation is a condition due to the end gas within the combustion chamber being spontaneously ignited by the heat generated by the advancing flame front,normal combustion ceases and an explosion occurs.Detonation is also referred to as knock...
On a single cylinder engine yes but with multiples you would need to be able to assign mass to the individual pins and webs, difficult on a straight six?
Peter 7307 has succinctly covered all aspects of introducing new technology. Too often these days new ideas are introduced that have no real advantage over their predecessors other than that they are new.I personally welcome new,useful and cost effective improvements providing they do what is...
You're dead right why bother to experiment with high tech if low tech works ok,all you need is an oil pipe and a drain for the turbo how difficult is that.
Besides the manufacturer can design it and make it and sell it just so Joe Public can abuse it and wreck it!
Over here we use pas pumps drawing oil from the base of the sump, float controlled anti aeration valves to allow only oil to return to the oil tank,a cooler & filter is also incorporated into the supply pipe to keep the oil cool & clean.
Perforated metal windage trays are also added to assist...
Leyland 350,600 & some versions of 680, Bedford 300/330
Ford Trader 4 & 6 cyl models, Some Perkins models too.
Admittedly these are late 50's early 60s.
The toyota system uses a butterfly controlled by a stepper motor controlled by ecu,designed for emissions rather than throttling in the conventional sense.
In my earlier life I worked extensively on trucks & coaches and pnuematic governors were common as indeed was a throttle set up to allow...
Essentially, on a N/A engine the volumetric efficiency remains fairly constant from idle to max governed speed eg approx 85-90%, however, in a turbo application this can be upto 150% and sometimes even greater dependant on design and application.
As previously mentioned a diesel runs without air...
I notice you still intend to use methanol as a secondary fuel, you really won't need it for moderate output as the oxygen & hydrogen content in the water will be sufficient the greatest advantage will be the internal cooling effect and increased density.
Hope you don't mind me saying
I would hazard a guess that all you want to do is to increase performance and reduce combustion temeratures if that is the case I would advise using only water with a dilute methanol screen wash aditive to prevent winter time freezing.
The discharge nozzle/s can be sited in the compressor inlet...
I would suggest controlling the air as it enters the compressor rather than trying to discharge high pressure hot air that has had considerable energy espended on it.
Assuming the throttle is between the compressor and the engine a secondary throttle body mounted up stream and ultimately...
You are spot on there is nothing quite like all the seemingly disorganised clatter,rumble and racket of big capcity engines, aero engines have a romance all of their own Pratt & Whitney,Wright and Rolls Royce and all the others too.
The shrill howl of a Merlin at speed is without doubt one of...
All things being equal multi point is better in power,economy and emissions and in injector location within the span of the inlet tract this then allows the throttle body to have a simpler location due to the absence of fuel pipes, although throttle potentiometer and other sensor wiring etc may...
