Which of the following is NOT included in the four-stroke cycle of a diesel engine? Choose the best answer. Intake Combustion Exhaust Spark Regarding gas engine combustion, which of the following statements is FALSE? Choose the best answer. Gas engines have a lower compression ratio than diesel engines Gas engines are basically diesel engines with different injectors Gas engines use an ignition module and spark plug Natural gas requires more heat than diesel fuel to ignite
Regarding gas engine combustion, which of the following statements is FALSE? Choose the best answer. Gas engines have a lower compression ratio than diesel engines Gas engines are basically diesel engines with different injectors Gas engines use an ignition module and spark plug Natural gas requires more heat than diesel fuel to ignite
Which statement relates to diesel combustion? Choose the best answer Diesel fuel requires a spark plug to ignite Diesel combustion and gas combustion are the same All statements relate to diesel combustion Compressed air gets hot enough to ignite diesel fuel
Diesel fuel combustion propagates as OA diffusion flame A premixed flame O both diffusion and premixed flame O neither diffusion nor premixed flame When comparing Dl and IDI diesel engines, the IDI diesel has O lower injection pressure and higher thermal losses O higher injection pressure and lower thermal losses O higher injection pressure and higher thermal losses O lower injection pressure and lower thermal losses The potential advantages and challenges of HCCl over more traditional combustion strategies are O...
How do engines transfer combustion into useable energy? Choose the best answer. Using heat from compressed air to ignite the air-fuel mixture By having several cylinders ignite in sequence By the piston moving up and down in a four-stroke cycle By converting reciprocating motion into rotary motion
Please choose the right answer for each question and circle it (1). Two stroke diesel engines are nomally applied in a) Trucks and Buses b) Cars c) Scooters and Sprinklers d) None of the above Q) The power output of four stroke engine is half of that two stroke engine for the same a) Engine displacement b) Engine speed c) Fuel consumption d) None of the above 3) Ifthe engine exhaust pressure is equal to the engine intake pressure then...
Which of the following choices accurately describe what makes one person different from another with regard to traits (such as height) that have a very high heritability? Choose all that apply ( you can select more than one or only one) Group of answer choices: Random factors during development is the most significant causes of differences between people None of the other choices are accurate What makes us different is not that we have different genes, but that we have...
In which of the following situations is ANOVA more powerful than ANCOVA? Choose one answer only. a. The adjusted means are the same as unadjusted means. b. The unadjusted means all have the same value. c. The correlation between the covariate and the dependent variable is strong. d. The correlation between the covariate and the dependent variable is weak.
Which of the following choices accurately describe what makes one person different from another with regard to traits (such as height) that have a very high heritability? Choose all that apply (can be more than 1 option, or maybe its just 1) Group of answer choices Most of us have exactly the same genes and alleles, and it’s the environment we were raised in that makes us different Random factors during development is the most significant causes of differences between...
