Abstract

A 'Blackburn Cycle' petrol engine 1 has maximised alternate 'air only' inductions between usual combustion cycles. The exhaust gases are passed through a condensing chamber 5 where steam produced by combustion is condensed to liquid and passes along the exhaust pipe 6 with other gaseous products of combustion, preferably entering into a condensate tank 7 which may also be a silencer at the rear of the vehicle. This tank preferably contains several porous or mesh surfaces 8 therein. Motion of the vehicle causes condensate 13 to splash and wet these surfaces which then filters, absorbs and reacts with unwanted products of combustion including NOx to improve exhaust emissions at low temperature. Preferably a reservoir 10 is also connected at a central point of the tank by means of a drain tube 9; a drain tap 11 may be operated remotely to empty the condensate in the reservoir. The exhaust gas treatment may also be used with diesel and Otto cycle engines.

Description

BLACKBURN CYCLE' ENGINE with EXHAUST CONDENSER
Background
Blackburn Cycle' engines have maximised alternate air only' inductions between usual combustion cycles at least some of the time.
An advantage of the 'Blackburn Cycle' is that an ideal combustion charge is created free from exhaust gas residue from the previous cycle. This is more fuel efficient but creates a higher combustion temperature which in turn produces more oxides of nitrogen (NOx). NOx is usually processed by a catalytic converter, but the cool 'air only' in the 'Blackburn Cycle' exhaust is unhelpful preventing the catalytic converter reaching its working temperature.
The present low temperature exhaust treatment invention is suitable for the Blackburn Cycle' because the alternate cool 'air only' cycles help to cool the exhaust and this improves condensing. This same exhaust treatment concept may also prove helpful for reducing NOx and other emissions in Diesel and usual petrol engines.
Description
There is a 'Blackburn Cycle' petrol engine which has maximised alternate 'air only' inductions between usual combustion cycles at least some of the time, where the exhaust gases are passed through a condensing chamber which is cooled by a coolant.
The coolant includes water, connected to the usual engine water cooling system or a separate lower temperature system. Air cooling is an alternative.
Steam produced by combustion is condensed to liquid and passes along the exhaust pipe with other gaseous products of combustion into a condensate tank near the rear of the vehicle. This tank has a relatively large surface area and contains vertical porous or mesh surfaces which have a capillary action. There is similar material on the top, ends and sides on the inside of the tank.
Liquid condensate in the condensate tank splashes due to the motion of the vehicle to wet and wash the large surface area of the porous or mesh material within the tank. The porous or mesh surfaces are wet with condensate which filters, absorbs and reacts with some of the products of combustion and improves the quality of the exhaust emissions.
The exhaust pipe enters the condensate tank from above so that exhaust pulsations also cause the condensate to splash and wet the porous or mesh surfaces while the vehicle is stationary.
A drain tube is placed centrally within the condensate tank at the optimum condensate liquid level to allow surplus condensate to drain.
Additional chemicals are added to the condensate tank to further improve the quality of the exhaust emissions.
A reservoir is connected to the condensate drain so that condensate can be stored and disposed of at a waste reception area, a filling station or into a loose container. A drain tap is remotely operated from the driving position or linked to a control for a fuel filler cap release.
This condensing exhaust system also offers advantages when used with Diesel engines and Otto cycle petrol engines An alternative condenser unit and condensate tank are one unit mounted close to the engine A separate high temperature exhaust treatment or a catalytic converter is an alternative used upstream of the condenser to further improve the quality of the exhaust emissions.
Plastic or other corrosion resistant components are suitable for use downstream from the condenser.
The condensate tank has additional cooling fins exposed to the moving air while driving.
The condensate tank also serves as a silencer.
