The knocking tendency in compression ignition engines for a given fuel will be Correct Answer Enhanced by decreasing compression ratio

The knocking tendency in compression ignition engines for a given fuel will be Enhanced by decreasing compression ratio.In SI engine, knocking tendency increases with increase in compression ratio. ... In CI engine, knocking tendency decreases with increase in compression ratio. If compression ratio is low in CI engine, there will not be enough temperature generation for ignition of the fuel air mixture.

A solid-oxide fuel cell is fed with carbon monoxide and reacts with air to produce CO2. This reaction will produce 2 electrons which are used to power an electric circuit external to the fuel cell. The reaction equation is shown below: 2CO(g) + O2(g) -> 2CO2(g) ΔHr° = -565.96 kJ/mol This reaction does not occur for other types of fuel cells which use a catalyst, such as polymerelectrolyte membrane or phosphoric-acid fuel cells. The presence of carbon monoxide on the anode side of these types of fuel cells will cause catalyst poisoning, reducing the efficiency and voltage of the fuel cell. Determine the rate of enthalpy change for a carbon dioxide production rate of 208 mol/hr. The extent of the reaction occurring in the fuel cell can be obtained by the following equation: where:
