“…As discussed by Klimstra (1989), failure to obtain a homogenous mixture at this point can cause significant cylinder-to-cylinder variations in the air-fuel ratio. According to Zastavniouk (1997), Klimstra (1989) and Lino et al (2008), this injection option can be increases emissions and the possibility of knock phenomena. Single point injection is use gaseous fuel injector to mix the gaseous fuel with the intake air in the manifold at one location for all cylinders of the engine.…”

“…The fuel coming from the tank supplies the pressure reducer before reaching the common rail and feeding the electronically controlled injectors. By supplying gas to the intake manifolds, injectors lead to the proper air/fuel mixture (Lino et al, 2008;Czerwinski et al, 1999;2993). The large volume of the common rail helps in damping the oscillations due to the operation of both pressure controller and injectors.…”

“…This has made estimation an important and active research area, which is especially true in the automotive area where cost is important, see (Lino et al, 2008;García-Nieto et al, 2008;Andersson and Eriksson, 2004) for some examples.…”

A systematic design method for reducing bias in observers is developed. The method utilizes an observable default model of the system together with measurement data from the real system and estimates a model augmentation. The augmented model is then used to design an observer which reduces the estimation bias compared to an observer based on the default model. Three main results are a characterization of possible augmentations from observability perspectives, a parameterization of the augmentations from the method, and a robustness analysis of the proposed augmentation estimation method. The method is applied to a truck engine where the resulting augmented observer reduces the estimation bias by 50 % in a European Transient Cycle.

“…The measurement result shows that for heavy-duty diesel vehicles without after treatment, that while CO 2 emissions dominate, CH 4 emissions account for between 0% and 0.11% and N 2 O emissions account for between 0.16% and 0.27% of the CO 2 equivalent green house gas emissions. Linoa et al (2008) studied the feasibility of the electronic control injection pressure in a new common rail injection system for CNG engine to prove that performances and pollutant emissions reduction can benefit from a precise control of the injection pressure. Present study was done on a gasoline engine, converted to run in a dual fuel mode operation.…”

Gasoline engines have proven their utility in light, medium and heavy duty vehicles. Concern about long term availability of petroleum and the environment norms by the increased vehicular emission have mandated the search for safe fuel. CNG is an environmentally clean alternative to the existing spark ignition engines with the advantages of minimum change. A higher octane number and a higher self ignition temperature make it an attractive gaseous fuel. The thermal efficiency is better than gasoline for the same engine. The reduced carbon mono oxide, carbon di-oxide, hydrocarbon emissions is a favorable outcome along with a slight increase in NO x emission when compared with gasoline fuel to a dual fuel mode in the existing spark ignition engines.The result from the experiment shows that CNG could be a potential substitute fuel that maintains performance and emissions characteristics in gasoline engines.
