Results: Spearman's correlation test showed that the
after-treatment SUV[sub]maxvalues were significantly correlated with the
after-treatment LDH, ESR, and CRP values (for LDH, ESR, and CRP, R2: 0.453, 0.426, and 0.351; P = 0.007, 0.012, and 0.042, respectively).
"A big differentiator for the brand is the Detroit Connect Virtual Technician remote diagnostics system, which is available as standard [and] helps fleets make informed service decisions within minutes of an engine or
after-treatment fault event, increasing uptime."
In order to detect these hidden problems in the Diesel engine, which directly affect the increase in its emissions, this paper has developed an optimal algorithmic model for system diagnostics of Diesel engines with electronic control exhaust gases
after-treatment and its abbreviated version is shown in Figure 1.
The company is leveraging new catalyst technologies and emissions control calibrations to enable downsizing of
after-treatment. OEMs benefit through retaining the same engine performance in a reduced package size.
The vehicle features diesel oxidation catalyst and selective catalytic reduction
after-treatment technology that do not require additional maintenance after installation.
Both comply with Tier 4 emission standards with modified diesel engines and
after-treatment technologies.
This includes the development of the new Ingenium engine (built inhouse at our new PS500m Engine Manufacturing Centre in Wolverhampton) and our advanced selective catalyst reduction (SCR) exhaust
after-treatment for NOX control which features on all 16MY vehicles.
Three different plans are available, offering a range of service from basic oil changes and 74-point inspections to more in-depth maintenance, including service for the exhaust
after-treatment system, transmission and chassis.
The gas-fired Caterpillar gensets, which were installed over the span of just 21 days, are engineered to emit only 250 mg/Nm3, even without
after-treatment.
GE Marine's breakthrough engine technology eliminates the need for a Selective Catalytic Reduction system (SCR) for exhaust gas
after-treatment and for storing or using urea aboard a vessel.
