1. Which engines can have their cylinders located below the crankshaft? Radial Engines In-Line Engines V-type Engines Opposed-Type Engines True or False: John Barber created the first practical heat engine. V-type engines have the least vibration in all types of reciprocating engine. Single-type radial engines can have 6 cylinders.

QUESTION 1 An Automotive Engineering company has à task to setup a diesel engine for a new vehicle model. The engine has four-cylinder, four-stroke and 3 liters of displacement volume that operates on the ideal diesel cycle with a compression ratio of 17 as shown in Figure 1. The engine uses light diesel fuel with a heating value of 42,500 kJ/kg and an air-fuel ratio of 24. You are the engineer in the company is given the following task to analyze the engine characteristics based on constant specific heats at 500 K, a) Evaluate all the working temperatures and pressures al all points on P – V diagram. b) Evaluate the thermal efficiency of the cycle. c) If the engine is plan to operate at 3000 rpm, evaluate the power rating produce by the engine.

1. Monatomic Engine -- What is the efficiency of this engine (see figure 4.9) if it were run with a monatomic gas (instead of a diatomic gas?) **23.1% is not right answer.** 2. Heat Pump -- Suppose now we run the triangle cycle (figure 4.9 above) in a reverse (counter-clockwise) cycle. If the gas is diatomic, what is the coefficient of performance for the heat pump used as a HEATER? Careful: remember that when the cycle is run counter-clockwise, the negative heats are now heats and the positive heats are now heats. A. 5 B. 10 C. 4 D. 9
