Due to the stricter and stricter European restrictions on diesel engines, fewer manufacturers produce vehicles fuelled by diesel and since not anyone affords new vehicles and the out-of-use diesel vehicle waste would be huge. New ways of improving the pollution levels on currently registered vehicles must be found. The article presents a novel approach focusing on this scope, starting with the basic actual engine, and developing by retrofitting up to mechanical and software upgrades, aiming to raise the output of mechanical characteristics and simultaneous reduction of exhaust pollution. In short, the paper is focusing on research regarding the effects of a diesel engine’s control unit retrofitting.

“…Thus, accidental admission of low-quality fuel leads to a high maintenance cost. 9 On the other hand, a mechanical-type injection system has been well proved in the industry. In addition, employing a mechanical injection system provides several benefits in terms of low manufacturing cost, low maintenance cost, and high robustness.…”

This paper shows development challenges for 11-liter heavy-duty off-highway diesel engines to meet Tier 3 emission regulations with a base diesel engine compliant with Tier 2 emission regulations. In the case of the installation of an exhaust gas recirculation (EGR) system for reduction of NOx emissions, there exists a risk of increased particulate matters (PM) emissions. An in-cylinder PM reduction is still necessary since a diesel particulate filter (DPF) after-treatment system is not under the consideration. The objective of this research is to see whether the base engine has a potential to meet Tier 3 emission regulations by changing in-cylinder configuration parameters including the bowl shape, injector position, the number of intake and exhaust valves, injector tip protrusion, and injector tip specifications such as nozzle spray angle and nozzle flow rate. These parameters are very important parts which enhance the air and fuel mixing process that helps the combustion process. Thus, the optimization of these design variables is essential to improve combustion efficiency and emissions reduction. In this study, the multi-dimensional computational fluid dynamics (CFD) code KIVA-3V is used to perform combustion simulations. The Kelvin–Helmholtz/Rayleigh–Taylor (KH-RT) model is employed for spray breakup and a reduced chemical mechanism for n-heptane is employed to simulate ignition delay and combustion of diesel fuel. To verify the simulation results, engine bench tests were performed with installations of the final version of in-cylinder geometry in C1-8 mode which is one of main test cycles to meet Tier 3 emission regulations. Finally, Tier 3 emission regulations have been met with the currently optimized in-cylinder configuration parameters.
