An internal combustion engine is provided in which the temperature of an exhaust gas gradually decreases from its upstream side to its downstream side, and the temperature of a working medium of a heat exchanger, which flows in the opposite direction to the exhaust gas, gradually increases from its upstream side to its downstream side. The temperature difference between the exhaust gas temperature and the working medium temperature is the smallest at the interface between a liquid phase region and a two-phase region of the working medium, and since a catalyst device is incorporated at the upstream side, relative to the flow of exhaust gas, of the vicinity of the position where the temperature difference is the smallest, it is therefore possible for the heat exchanger to utilize the heat generated by the catalyst device effectively. Since the catalyst device is disposed in the two-phase region of the working medium, in which the temperature is constant, and this constant temperature is a temperature at which the catalyst is active, the catalyst can exhibit a stable exhaust gas purification performance.

Internal combustion engine

Evaporator temperature control means (U) that, in order to make the temperature of steam generated by heating water using exhaust gas of an engine coincide with a target temperature, controls the amount of water supplied to the evaporator based on the flow rate of the exhaust gas, the temperature of the exhaust gas, the temperature of the water, and the temperature of the steam. Calculating an exhaust gas flow rate (Gmix) based on a fuel injection quantity, an air/fuel ratio, and a rotational speed of the engine improves the precision and the responsiveness of the calculation. Controlling the amount of water supplied to the evaporator based on this exhaust gas flow rate (Gmix) therefore improves the accuracy with which the steam temperature is controlled so as to make it coincide with the target temperature.

In a vehicle designed so that a driven wheel is driven by uniting an output from an engine and an output from a Rankine cycle system to each other, an accelerator pedal and a throttle valve are connected electrically to each other by a DBW control unit. When an accelerator opening degree (&#x3b8;ap) commanded by a driver is increased, a throttle opening degree (&#x3b8;th) is increased by a correcting amount (&#x394;&#x3b8;th) more than a value proportional to the accelerator opening degree (&#x3b8;ap), thereby compensating for an output shortage due to a response delay of the output from the Rankine cycle system. When the accelerator opening degree (&#x3b8;ap) commanded by the driver is decreased, the throttle opening degree (&#x3b8;th) is decreased by the correcting amount (&#x394;&#x3b8;th) more than the value proportional to the accelerator opening degree (&#x3b8;ap), thereby compensating for an output excessiveness due to the response delay of the output from the Rankine cycle system.

A small capacity pre-catalytic system ( ) is disposed immediately downstream of an exhaust port ( ), and a large capacity main catalytic system ( ) is disposed immediately downstream of the pre-catalytic system ( ). The pre-catalytic system ( ) includes finely divided catalyst supports ( ), and a third stage heat exchanger (H ) is disposed between these catalyst supports ( ) so that a heat transfer tube ( ) is bent in a zigzag manner. Fourth stage and fifth stage heat exchangers (H , H ) are disposed on the upstream side, in the flow of the exhaust gas, of the pre-catalytic system ( ), and first and second stage heat exchangers (H , H ) are disposed on the downstream side, in the flow of the exhaust gas, of the main catalytic system ( ). Water is made to flow through the first stage heat exchanger (H ) to the fifth heat exchanger (H ) in a direction opposite to that in which the exhaust gas flows, thereby exchanging heat with the exhaust gas. This allows the catalyst temperature to be actively controlled within the optimal temperature range without degrading the energy efficiency of the entire system.

A waste heat recovery system for an internal combustion engine. The internal combustion engine includes first and second raised temperature portions. The raised temperature is higher at the first portion than at the second portion. A first evaporating portion generates a first vapor from the first raised temperature portion. A second evaporating portion generates a second vapor from the second raised temperature portion and with a lower pressure than the first vapor. First and second energy converting portions of a displacement type expander converts expansion energy of the first and second vapor into mechanical energy. A condenser and a supply pump are also provided.

In a drive system, there is provided a waste heat recovering device forming a Rankine cycle by an evaporator for heating water with waste heat of an internal combustion engine to generate high-pressure vapor, the internal combustion engine being connected to a transmission, a displacement-type expander for converting high-pressure vapor generated by the evaporator to an output with constant torque, a condenser for liquefying low-pressure vapor discharged from the expander, and a feed pump for supplying water liquefied by the condenser to the evaporator. The expander is connected to a power generator/motor via a planetary gear mechanism, and the expander is connected to an output shaft of the internal combustion engine via the planetary gear mechanism and a belt-type continuously variable transmission. A change gear ratio of the belt-type continuously variable transmission is controlled such that a rotational speed of the internal combustion engine and a rotational speed of the expander are matched with each other and are transmitted to the transmission. Hence, it is possible to effectively drive the driven portion by using the output of the expander of the waste heat recovering device.
