Quantification of the Formaldehyde Emissions from Different HCCI Engines Running on a Range of Fuels
(2005) In SAE Transactions, Journal of Fuels and Lubricants 114(4). p.1347-1357- 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)
