Effect <strong>of</strong> control schemes on performance and emissions<br />
Findings <strong>of</strong> the Intelligent Engine measurements<br />
• For the RPM variation it was shown that the same tendency is observed for all<br />
loads, with a clear trend that higher RPM results in a lower NOx level.<br />
• For the Pmax variation and the Pcomp/Pscav variation the relation is close to<br />
linear, but with the gradient depending <strong>of</strong> the engine load.<br />
• Blow back variation did not have a significant influence on NOx emission, but<br />
remains an important factor with regard to scavenge efficiency and cleanness<br />
<strong>of</strong> the scavenge space.<br />
• The hydraulic pressure influenced both the fuel injection pressure and the<br />
opening <strong>of</strong> the exhaust valve.<br />
