are spark plugs really required all the time???????

All diesel engines are equipped with a glow plug or the heater as it is known. When the ignition is switched on, the glow plug brings the combustion chamber to proper temperature (i think its 800 c) prior to the engine being cranked.

BTW in Kargil sectors and all, the bulldozers and other critical equipments are kept running throughout the peak winter season to prevent other fluids like oil, coolant etc from freezing.

exactely diesel engines have heater plugs(glow plugs) to heat the engines in the mornings, in places where it is really really cold like canada n all , the blocks of the engines are plugged in to a heater, connected to a wall socket, it is cheaper than running the engine all the time(like throughout the night), these devices are called Block Heaters.

That remids me of my college days when a friend of mine used to drive a Diesel Jonga. Remember lighting a kerosene stove to boil water under the oil pan and then pouring the boiling water over the block to start the monster up.

It is practically impossible to produce a sparkplugless engine.. Have you ever heard a Petrol Engine without a Sparkplug..

I really doubt.

I know Indica had glow plugs ...I had to wait for the glow plug timer to go off before cranking the engine which typically took about 10 sec. Alleast one glow plug used to fail every 18months. I used to carry one spare plug with me always !.

For my Diesel Innova , there is no glow plug indicator and I am allowed to crank the engine without any waiting. So is it possible that CRDI engines dont need glowplugs ? Has it got anything to do with Direct injection ?
