A stop range changing unit changes an engine stop range, which is a cruise range in which an operation of an engine is stopped, based on a type of fuel that is burned in the engine and that is determined by a fuel type determination unit. Therefore, the engine is stopped or started up under a cruise condition that suits the fuel type. Accordingly, even if start-up performance of the engine varies due to variation of the fuel type, unfavorable effects of the variation in the start-up performance of the engine on a smooth motion of a hybrid vehicle is alleviated.

An ejector, such as a venturi, facilitates the delivery of gaseous fuel to the combustion chamber of a burner. A blower forces air through the ejector, and the air flow produces a suction that draws fuel from a fuel inlet to produce a fuel-air mixture. The amount of fuel drawn from the fuel inlet is a function of the air flow such that a substantially constant fuel-air ratio is obtained over a range of air flow rates and temperatures without the need for a separate high-pressure fuel pump. The fuel-air mixture may be provided to a combustion chamber for combustion. Air from the blower may be pre-heated prior to entering the ejector, for example, using a heat exchanger that recovers some of the heat from the combusted fuel-air mixture. Air flow through the ejector may be conditioned, for example, by a swirler, to produce a tangential air flow that can increase fuel flow by increasing air velocity across the fuel inlet and/or produce a swirl-stabilized flame in the combustion chamber. The combusted fuel-air mixture may be provided to a thermal load, such as an external combustion engine. Blower speed may be controlled manually or automatically to control power output. Fuel flow to the ejector can be controlled manually or automatically to control fuel-air ratio. The burner can be configured to operate with multiple fuel types, for example, using a fuel selector with fixed or variable restrictors.

A fuel control system for controlling the use of primary fuel and alternate fuel in an internal combustion engine without cross-contamination of fuel types. Cross-contamination of fuel types may eliminate the ability to receive certain benefits or financial incentives associated with use of alternate fuel, including but not limited to RINs, credits, and subsidies. In one embodiment, primary and/or alternate fuel are controllably delivered from sources to a flow cell. If blending is desired, both primary and alternate fuels are delivered to the flow cell. The engine is fed with the resulting primary fuel, alternate fuel, or blended mixture of fuel from the flow cell. The flow cell contains a bypass inlet port adapted to receive excess fuel not consumed by the engine in lieu of the excess fuel being returned to the primary and/or alternate fuel sources. In this manner, cross-contamination of the fuel sources can be avoided.

A method for determining an optimal combustion interval during start-up of a hydrocarbon catalytic reformer under various conditions of temperature, fuel type, and combustion fuel flow rate. An initial catalyst temperature is measured and an algorithm is used to calculate a rate of heating of the catalyst by combustion based upon heat content of the fuel, selected fuel flow rate, and heat capacity and mass of the catalyst and reformer passages. From the initial temperature and the heating gradient, an optimal combustion interval is inferred through the algorithm and used to terminate combustion, initiate a combustion quench interval, and change over the fuel flow rate and mixture from combustion to reforming.

While the materials compatibility challenges have largely been met in “flex-fuel” vehicles, the engine and aftertreatment operation has not been optimized as function of fuel type (i.e. ethanol, biodiesel, etc.). The full-scale introduction of alternative fuels is most likely going to occur as blends with conventional fuels. This is seen to some extend with the limited introduction of E85 (85% ethanol, 15% gasoline) and B20 (20% biodiesel, 80% conventional diesel.). This further exacerbates the challenge of accommodating variable fuel properties, as there will be differences in combustion properties due to both the type of alternative fuel (i.e. pure biodiesel vs. pure diesel) and blend ratio (i.e. B20 vs. B80). Real-time estimation of the fuel blend is key to the optimized use of two-component fuels (e.g. diesel-biodiesel, gasoline-ethanol, etc.). The approach outlined here uses knowledge of the exhaust composition, fuel and air delivery rates to the engine to estimate the fuel blend. The strategy is illustrated with a production wideband O₂ in the engine's exhaust stream, coupled with the knowledge of the air-fuel ratio, to estimate the percentage of biodiesel in fuel being delivered to a 2007 Cummins turbo-diesel engine.
