Answer Posted / kameshver prasad
A four stroke engine is more efficient than 2-stroke due the
following reasons:-
1.)For the same size of cylinder, Some of the power and
compression stroke get wasted due to the presence of ports.
Improper combustion due to the mixing of burnt gases with
fuel.
2.)The fuel consumption is four stroke is less and the
combustion power in four stokr engine is greater there by
reducing the emmission of smellier gases.
3.)prescence of valves which precisely control the flow of
charge into the chamber and exit the exhaust gases with
proper timing which is hard to achieve by ports in a 2
stroke engine.

Hai, iam renjith. my qtn about the calorex heat and cool pump. What is the reason of the above machine is trip on high pressure. r134a gas using in this system. 8 months old. model is calorex propac 90(3 phase). This system has 2 compressor. Both are starting on 13amps after that rise up to around 21 within 1 minute. After will be trip on high pressure. Showing 68 psi in suction side on standby mode. Can i have a solution without delay?
