6. Conclusion and Recommendation
6.1. Conclusion
• Dual Turbocharges and Dual Air-to-Water Charge-Air-Coolers
• The use of solenoid valve controlled injectors allows three injections per cycle.
• Glow plug is to heat the intake air by vaporizing and igniting fuel in the air inlet
duct.
• Aftertreatment
6.2 Recommendation
• Longer time for practice especially on diesel engine
• Spread this learning material to student in specialized classes
