Cummins V903 Diesel Engine

A. YES, 60mph > 55mphB. NO, 64mph < 65mphC. YES, 64mph > 55mphD. NO, 60mph < 65mph

Can you help with question1

P1:{{ 1%VO KOREK TELECOMIKOREK Asiacell The engine shown in the picture may be called 8-cylinder inline engine. 6-cylinder V-engine. 4-cylinder V-engine. O محو التحديد 4-cylinder inline engine. 8-cylinder V-engine. 6-cylinder inline engine.

If the range of the aircraft needs to be increased to 8000km from 6000km what changes to the engine would you consider to be appropriate?

Can you please help me with ONLY the C,D, and E parts of this question? I would appreciate any insight or explanation on the final 3 parts only.  I asked this question already but I got an explanation of the first 3 instead of the final. lol. Thank you! For C, I understand that Th>Ti>Tc, does this mean that since the ec=1-Tc/Th that the efficiency won't change with having two engines because we are using the same temps?

Two automobile engines have the same total displacement volume and the same total power produced within the cylinders. List the possible advantages of: (a) A V6 over a straight six. (b) A V8 over a V6. (c) A V6 over a V8. (d) An opposed cylinder four over a straight four. (e) An in-line six over an in-line four.

I am having a hard time understanding C-E on this problem. For C, I know that Th>Ti>Tc. Does that mean that since ec= 1-Tc/Th and Tc is the lowest temp of the system, that it is indeed more efficient with both engines?  The other ones, I just don't know where to start.  Any help or explantions would be appreciated!

Using the basic relations given below and detailing your method and assumptions,Develop all the analytical relations required to:1) Determine the temperatures and pressures at all stages of an ideal air-standard SIOtto cycle analysis2) Show that the thermal efficiency of any internal combustion engine can besimplified as a ratio of temperature differences 3) Discuss the concept of Brake Specific Fuel Consumption (BSFC) and propose a rationale for the Figure 1 below (in other words, explain why the BSFC is decreasingbefore increasing with engine speed)

A comparison between the actual gasoline engine and actual diesel engine is to be made. Assume the  heat added is the same.  Check all that apply. Group of answer choices Because the diesel engine has a lower compression ratio the thermal efficiency will be higher because less work is required to compress the air. Because the diesel engine can run a higher compression ratio the thermal efficiency will be higher. Because the diesel engine has a higher efficiency, it reponds quickly to rapid accelerations and in-city driving conditions compared to a gasoline engine. The diesel engine compresses only air on the compression stroke and is not knock limited so the compression ratio can be much higher The gasoline engine is knock limited and the compression ratio will be lower than the diesel engine The gasoline engine compresses only air on the compression stroke and is not knock limited so the compression ratio can be much higher

(d) A generator spins at 3600 rpm. Convert that rotational speed to units of rev/s. (e) A generator spins at 3600 rpm with a torque of 200 N m. In SI units what is the power? (f) An automobile engine produces 94 kW at 6300 rpm. In SI units, what is the torque? (g) An automobile engine produces 221 lb ft of torque at 1800 rpm. In Hp, how much power does this engine produce?
