MIDTERM EXAMINATION 4384208

by Grace Balahay
1

is a device which when provided with fuel and air, produces rotary power

Written answer

2

is the volume that a piston displaces in one stroke inside the cylinder. It is equal to the cross-sectional area of the piston multiplied by the length of the stoke

Written answer

3

is the product of the piston displacement per cylinder and the number of cylinders

Written answer

4

is an engine characteristics related to engine efficiency, that is, the ability of the engine to convert in the fuel to useful mechanical energy

Written answer

5

is the volume of the space inside the cylinder above the piston when it is at the top dead center (tdc) position

Written answer

6

is the ratio of the total volume inside the cylinder to the clearance volume

Written answer

7

also known as the limited pressure or mixed cycle, trinkler cycle, seiliger cycle or sabathe cycle

Written answer

8

is a thermal cycle that is a combination of the otto cycle and the diesel cycle, first introduced by russian-german engineer Gustav Trinkler

Written answer

9

heat is added partly at constant volume and partly at constant pressure, the advantage of which is that more time is available for the fuel to completely combust

Written answer

10

is presented which includes a combination of two engines different cycle pressure ratios. The two engines are cross connected by a common regenerator that enables low specific fuel consumption under partial load conditions.

Written answer

11

was invented in 1982 by Kenneth W. Porter, P.E.M.S.A.E, of King Country, Washington. It operates on a modified Brayton cycle, but with continuous pulsed combustion, similar to that of a gas turbine. It can burn most commonly available hydrocarbon fuels and features the high compression ratio (14:1) typical of a Diesel cycle.

Written answer

12

on the rear of the rotor connects to a layshaft spur gear and provides the output shaft drive to the connected load

Written answer

13

enclosing the single combustion chamber, and its co-axial slotted sleeve carried by the rotating cylinder barrel. This feature enables the charging air to enter the combustion chamber and allows evacuation later of the products of combustion to the expander cylinder and pistons.

Written answer

14

is a machine delivering power or thrust. It does this using a gaseous working fluid.

Written answer

15

burns the fuel in a burner and delivers the resulting gas to the power section, where it spins the power turbine

Written answer

16

consists of a compressor which has a rotor with a series of blades around its outer edge

Written answer

17

is a heat engine developed by Wally Minto. The engine consist of a set of sealed chamber arranged in a circle, with each chamber connected to the chamber opposite to it.

Written answer

18

operates on a small temperature gradient, and produces a large amount of torque, but at very rotational speed

Written answer

19

is a heat engine operating by cyclic compression and expansion of air or gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work

Written answer

20

is traditionally classified as an external combustion engine, as all heat transfer to and from the working fluid take place through the engine wall

Written answer

21

is a type of internal combustion engine using a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons.

Written answer

22

invented wankel engine

Written answer

23

For gasoline engines, is classified as a highly-combustible fuel together with high octane gasoline

Written answer

24

for diesel engine, is classified as less combustible together with bunker fuel and kerosene

Written answer

25

from the fuel tank, the gasoline passes through the _____ where gasoline is mixed with air before it enters the cylinder via the inlet valve

Written answer

26

in diesel engine, the gasoline passes through the ______ where it is pressurized before entering the cylinder via the fuel injector nozzle

Written answer

27

compression ratio of diesel engine

Written answer

28

compression ratio of gasoline engine

Written answer

29

invented britalus rotary engine

Written answer

30

invented the minto wheel

Written answer

31

built the first engine
