Abstract
In this paper, the formaldehyde emissions from three

different types of homogenous charge compression

ignition (HCCI) engines are quantified for a range of

fuels by means of Fourier Transform Infra Red (FTIR)

spectroscopic analysis. The engines types are

differentiated in the way the charge is prepared. The

characterized engines are; the conventional port fuel

injected one, a type that traps residuals by means of a

Negative Valve Overlap (NVO) and finally a Direct

Injected (DI) one. Fuels ranging from pure n-heptane to

iso-octane via diesel, gasoline, PRF80, methanol and

ethanol were characterized.



Generally, the amount of... (More)
In this paper, the formaldehyde emissions from three

different types of homogenous charge compression

ignition (HCCI) engines are quantified for a range of

fuels by means of Fourier Transform Infra Red (FTIR)

spectroscopic analysis. The engines types are

differentiated in the way the charge is prepared. The

characterized engines are; the conventional port fuel

injected one, a type that traps residuals by means of a

Negative Valve Overlap (NVO) and finally a Direct

Injected (DI) one. Fuels ranging from pure n-heptane to

iso-octane via diesel, gasoline, PRF80, methanol and

ethanol were characterized.



Generally, the amount of formaldehyde found in the

exhaust was decreasing with decreasing air/fuel ratio,

advanced timing and increasing cycle temperature. It

was found that increasing the source of formaldehyde

i.e. the ratio of heat released in the cool-flame, brought

on higher exhaust contents of formaldehyde. The

application of a standard three-way catalyst completely

removed formaldehyde from the exhaust stream. (Less)
