摘要:
A fuel consumption evaluation system capable of quantitatively determining whether an operation saving a fuel is performed or an operation wastefully consuming the fuel is performed in an averaged way of operation, instructing, in consideration of also a change in the overall weight of a vehicle, a specific fuel-saved operation to a driver and/or an operation administrator based on the data thus determined, and attracting attention and instructing the driver on the fuel-saved operation in real time. The evaluation system comprises a control means evaluating a fuel consumption by using a measured engine rotational speed, an accelerator opening, a vehicle speed, and a fuel flow rate. The control means further comprises a storage means and is characterized in that an area from the start of running to the stop is grouped into multiple areas, a parameter on fuel consumption are set for each of the multiple areas, and based on a correlation between the parameters and the fuel consumption, a fuel consumption for each of the multiple areas is determined, and the evaluation is made based on the determined fuel consumption.

Dispositif de mesure de la consommation de carburant des moteurs des véhicules automobiles. Ce dispositif interactif comporte un boîtier électronique (16) installé dans le compartiment-moteur et un micro-ordinateur de poche (54) amovible, installé dans l'habitacle. Le boîtier (16) reçoit les impulsions de consommation et de parcours produites par un calculateur d'injection (10) et un capteur de parcours (22) entraîné en rotation par un câble flexible (24). Le boîtier (16) adresse périodiquement au micro-ordinateur (54) les nombres N et M d'impulsions compter pendant une période donnée. Le micro-ordinateur (54) calcule et affiche sur son écran (58) les consommations instantanées et/ou moyenne, à l'heure et aux cent kilomètres, à partir de facteurs de calibration des impulsions de consommation et de parcours F e et Fp calculés à la demande, sur instructions de l'opérateur. Application à la vérification de tous moteurs à injection en garage et ateliers d'usine.
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 fuel consumption saving drive supporting device which calculates a mileage of each driver and informs each driver of advice based on an increase or a decrease of the calculated mileage is disclosed. The fuel consumption saving drive supporting device extracts a drive operation of the driver or a drive condition of a vehicle of the driver for increasing the mileage, and informs the driver of the advice in the drive operation or the drive condition corresponding to the extracted drive operation or the extracted drive condition.
摘要:
The present invention is intended to provide a fuel consumption evaluation system which obtains quantitative data to determine whether actual driving has consumed fuel more efficiently or less efficiently than average driving and gives the driver and/or manager concrete advice for fuel-efficient driving based on the obtained data, and also provide a fuel consumption evaluation system which decides, based on obtained fuel efficiency data, whether driving is more fuel-efficient than average driving and sets a target and gives the driver and/or manager concrete advice for fuel-efficient driving based on the obtained data in consideration of change in vehicle total mass without any influence of slopes and traffic flows and particularly encourages and instructs, in real time, the driver to do fuel-efficient driving. The system comprises: engine speed measuring means (2) which measures engine speed of a truck (1); accelerator opening degree measuring means (3) which measures an accelerator opening degree (α); vehicle velocity measuring means (4) which measures vehicle velocity (V) ; fuel flow rate measuring means (5) which measures a fuel flow rate (Fw) ; and control means (10) which evaluates fuel consumption of the truck from measured engine speed (N), accelerator opening degree (α), vehicle velocity (V) and fuel flow rate (Fw). The control means, which has storage means (11), divides a run from start to stop into plural phases (start acceleration phase E1, steady running phase E2, deceleration phase E3, idling phase E4), sets fuel consumption-related parameters ("start acceleration shift-up engine speed N1 and start acceleration accelerator opening degree α1" P1, "steady running engine speed N2" P2, "deceleration coasting ratio" P3 and "idling velocity V4" P4) for each of the plural phases (E1-E4, determines fuel consumption (Q) for each of the plural phases (E1-E4) based on correlation (correlation line F in Fig.5) between the parameters (P1, P2, P4) andfuelconsumption (fuel consumption per unit distance traveled q), and makes an evaluation based on the determined fuel consumption (Q).
