I live in Ukraine, "before last" winter one time was -32 C, but usually about -10 ... -20 C.
i plan to start small business, produsing and installing equipment for using E100 and E85 on usual cars.
it will be "impulse wideners" and/or reprogramming of ECU - becouse its universal for many types of cars and installing and deinstalling without traces - our car dealers can stop warranty for car if any electric units are installed NOT in their services.
and i have to develop a preheater for cold starting - so i cant deside what to heat - fuel or air.
fuel heater may be like biodieselers do - heating by glowwire fuel ramp or injectors, not to very high temp.
air heater may be like ring with ceramic or wire heater between intake collector and MAF sensor - it easy installing and deinstalling
or plase diesel glow "spark plug" in each tube of intake collector near the intake valve and limit its temp by resistor or other way. it cant be uninstall easilly and traceless, but i think its better solution.
driver tunrs on ignition and do noot turn on the starter - glow plugs heats air in intake collector by 30 - 45 sec - and switching off becouse they takin much electricity and it is no good for starter. driver starts engine - intake collector contains 1-2 liter of warmed air, it is enough to start engine.
before intake filter will be the thermostat like this - it will mix cold outside air and hot air, taked near output collector and automatically keepeng temp 25 C - its cheap and do not using electricity, there is bimetall plate inside. but it can warm air only after engine starts and output collector warms up.

code of thermostat is 2108-1143010
So question is: what to heat? what better: ingection of cold fuel in cold air of intake collector or injecting cold fuel with warm air?
