Summary:

The conventional internal combustion engines continue todominate many fields like transportation, agriculture and powergeneration. Moreover, apprehension over oil price restriction hascreated an unprecedented demand for fuel economy. Diesel engine ismostly preferred for its higher thermal efficiency, high-torque andoutstanding longevity. In recent days with flooded technologies,Uniqueness and the Differentiation of Product play vital role for asuccessful business in Auto Industry. However, there is alwaysdemand for low cost solutions and the product should be easilyacceptable the end-user. The present development study is relatedto the Challenges of Design and Development of Internal CombustionEngine to meet the stringent Emission and Performance requirements(BS-IV and upgradable for BS-VI) with Diesel Fuel and moreparticularly to achieve the targets with conventional FuelInjection Systems (Non-electronic Fuel Injectors, In-Line FuelInjection Pump-Governed Electronically) with required sub-systems.This is a unique approach for diesel engines for current andnear-future requirements (emissions and performance) withcost-effective and ease of customer acceptance. While developingthe FIE system with In-line Fuel Injection Pump, the study focusedon influence of the parameters such as cam-velocity, fluctuation ofsupply fuel pressure, plunger-barrel clearances, fuel pressureacross pump-speeds, anchor residual clearance and at Injector sidevalve matching clearance, valve lift, injector opening pressure,nozzle flow coefficient, injector needle lift. The developmentincludes the selection and optimization of Non-Electronic injectorswith suitable hole-size and number of holes, The Fuel Injectionpressure and delivery valve in conventional In-line Fuel Injectionpump with static timing throughout the engine operation. Thecooled-EGR is optimized to meet reduced NOx level with static fuelinjection timing through-out the testing cycle. The PM level wasbrought down by optimizing injection pressure along with adaptationof low-cost Partial Oxy Cat-con (passive regeneration). Thedevelopment was focused to certify the engine for an automotiveapplication with latest emission norms, the IOBD-II requirementsalso considered and suitable algorithm and logic were developedwith small ECU. The Developed engine with Inline FIP technology wasproved both at Engine-level (Power, Torque, Emissions, BSFC,Durability) and at Vehicle-level (Drivability, on-road FuelEconomy) and it was resulted with at par to better than Common RailSystem, the base engines, but at reduced engine cost with ease ofcustomer acceptance with respect to maintenance at long-use of thevehicle. The same engine with simple FIE system has been verifiedfor Off-Highway applications with BS-V (CEV / Trem V equivalent)requirements
