Bosh fuel injection pump is an example of _______________ type fuel injector pump.

Correct Answer: jerk
Bosh fuel injection pump is an example of jerk type fuel injector pump and not distributer type.

In a diesel engine
1. Fuel injection pump is used
2. Fuel injection pump and carburettor is used
3. Fuel injector is used
4. Neither fuel injection pump nor injector is used

Which of the following is defined as the difference between the governor cutoff speed at which the fuel delivery stops with the increasing injection pump speed and the cut-off speed at which point fuel delivery just restarts with the decreasing injection pump speed?

How is the fuel injection time controlled in a distributor type fuel injection pump?

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:

In an electronic fuel injection system, the ECU calculates the optimum fuel injection volume for the current engine condition based on data from a wide range of sensor, and it injects this volume of fuel into the intake manifold at the optimum timing.

If the gear ratio for fuel pump is thrice that of the oxidizer pump, the shaft speed of fuel pump is ____________ the oxidizer pump.

In MPFI-Electronic system, at the time of starting, the cold start injector is operated by the cold start injector time switch.

Non-impinging injector is also called as _________ injector.

In a fuel-injection system, the amount of fuel delivered into the air stream going to the engine is controlled by a pump which forces the fuel under pressure.

With reference to 'fuel cells' in which hydrogen rich fuel and oxygen are used to generate electricity. Consider the following statements.
1. If pure hydrogen is used as a fuel, the fuel cell emits heat and water as by products.
2. Fuel cells can be used for powering buildings and not for small devices like laptop, computers.
3. Fuel cells produce electricity in the form of Alternating Current (AC).
Which of the statements given above is/are correct?
