1.	Which of the following helps in the increase of the engine torque at lower engine speeds?(a) Throttle body injection(b) The common rail injection system(c) Port injection(d) Retarded post-injectionI have been asked this question in class test.Query is from Modern Common Rail Fuel Injection System topic in division Diesel Engine Fuel Supply System of Automotive Engine Design
Answer» Right ANSWER is (b) The common rail injection system To explain: The common rail injection system, the injection PRESSURE is possible even at low engine speeds which leads to more COMPLETE combustion of the fuel. It ALSO increases the engine torque in the lower engine speed ranges.
