摘要:
A multipoint ignition engine (1) includes a central electrode pair (9), disposed in the center of a combustion chamber (2), for forming a central spark gap (10), and a plurality of peripheral electrode pairs (12) held in a head gasket (15), which has an opening portion having a substantially identical diameter to an opening portion of a cylinder (5) in a position corresponding to the opening portion of the cylinder (5), for forming a plurality of peripheral spark gaps (13) around the inner periphery of the opening portion in the cylinder (5). An air-fuel mixture in the combustion chamber (2), which is obtained by mixing together fuel and air evenly to the stoichiometric air-fuel ratio or a richer/leaner air-fuel ratio than the stoichiometric air-fuel ratio, is ignited using both the central spark gap (10) and the plurality of peripheral spark gaps (13).

The evaluation system for vehicle operating conditions comprises an automatic control device (10, 27) for setting target vehicle operating conditions and controlling the vehicle so as to achieve the target operating conditions, and a display device (4) mounted on the vehicle. The system determines whether operation that worsens fuel economy has been performed or not on the basis of the operating conditions of the vehicle; determines the operating state of the automatic control device (10, 27) based on the operating conditions of the vehicle; computes the excess fuel consumption, which is the fuel amount consumed in excess by operation that worsens the fuel economy, based on operating conditions of the vehicle and the operating state of the automatic control device (10, 27); and displays the computed excess fuel consumption to the display device (4).

A multipoint ignition device comprises: a head gasket (1) interposed between a cylinder head and a cylinder block of an engine, having an opening (3) in a position corresponding to a cylinder opening portion; and a plurality of intermediate members (6) connected respectively to a plurality of electrode pairs (2) and held in the head gasket (1). Respective heat values of the plurality of electrode pairs (2) are set individually by varying the contact area between the plurality of intermediate members (6) and the head gasket (1) according to the respective disposal positions of the plurality of intermediate members (6).
摘要:
A computing unit 3 of an analysis device 1 calculates a weight of fuel consumed by an engine 10 based on the weight of intake air and air fuel ratio of an engine of a vehicle to be analyzed detected by an air flow meter 14 and an air-fuel ratio sensor 16, and computes a fuel consumption rate based thereon and the running distance. The computation of fuel consumption rate does not require an injection pulse signal, so the fuel consumption rate can be precisely computed even for a vehicle which does not have an injection pulse signal such as a non-EGI vehicle or a diesel engine vehicle.
摘要:
A plurality of electrode pairs (P1 to P8) are caused to project from a side wall of a combustion chamber (2) of an engine, and a distance between ignition gaps (G1 to G8) and the side wall of the combustion chamber (2) is varied according to the positions of the plurality of electrode pairs (P1 to P8).

The evaluation system for vehicle operating conditions comprises an automatic control device (10, 27) for setting target vehicle operating conditions and controlling the vehicle so as to achieve the target operating conditions, and a display device (4) mounted on the vehicle. The system determines whether operation that worsens fuel economy has been performed or not on the basis of the operating conditions of the vehicle; determines the operating state of the automatic control device (10, 27) based on the operating conditions of the vehicle; computes the excess fuel consumption, which is the fuel amount consumed in excess by operation that worsens the fuel economy, based on operating conditions of the vehicle and the operating state of the automatic control device (10, 27); and displays the computed excess fuel consumption to the display device (4).
摘要:
A calculation unit (3) determines whether or not an operation which worsens fuel economy has been performed, and if it is determined that an operation which worsens fuel economy has been performed, the calculation unit (3) respectively calculates the actual amount of consumed fuel and an amount of fuel that would have been consumed had the operation that worsens fuel economy not been performed. The calculation unit (3) then calculates an amount of fuel consumed in excess due to the operation which worsens fuel economy by subtracting the amount of fuel that would have been consumed had the operation that worsens fuel economy not been performed from the actual amount of consumed fuel. A display (4) displays the calculated excess fuel consumption amount.
摘要:
An operation management system is provided, which includes a database (105) that accumulates operation information, including a fuel consumption amount, that is gathered from a running vehicle (A1 to B2) through a network (20); and a management device (103, 104) that sends the gathered operation information and the operation information accumulated in the database (105) to a client computer (A10, B10) through the network (20). The management device (103, 104) receives an instruction for the vehicle (A1 to B2) from the client computer (A10 and B10), and sends the received instruction to the vehicle (A1 to B2).
