An exhaust upstream section () of an exhaust apparatus (E) comprises a plurality of branch pipe portions (), a plurality of intermediate collector pipe portions (), a final collector pipe portion (), and an exhaust gas-purifying unit (). The exhaust gas-purifying unit () is disposed on a vehicle-rear side of an engine () to allow a gas passage thereinside to extend approximately in vehicle-widthwise direction, in top plan view. Each of the plurality of intermediate collector pipe portions () curves to allow an exhaust downstream region of the intermediate collector pipe portion () to be oriented toward one side or the other side of the vehicle-widthwise direction, in top plan view, and the final collector pipe portion () curves to allow an exhaust downstream region of the final collector pipe portion () to be oriented toward a vehicle-front side, in top plan view.

Exhaust apparatus for transverse engine

A hot wire type flow sensor having a cylindrical housing to be placed in a fluid passage, a plurality of hot wire supporters mounted on the inner surface of the housing, a hot wire stretched between the supporters, and a control circuit connected to the hot wire to output a signal in proportion to a flow rate of fluid. The inner surface of the housing at the upstream side of the hot wire is so formed that the flow of the fluid is concentrated at the central part of the hot wire.

A fuel control apparatus comprises a fuel supplying means for supplying fuel to an internal combustion engine depending on the operation of a fuel control valve, a hot-wire type intake air quantity sensor disposed in an air-intake passage for the internal combustion engine to detect the quantity of air passing therethrough, a memory means which is adapted to accumulate an output from the intake air quantity sensor, the number of revolution of sand internal combustion engine, or the length of time in operation of the internal combustion engine, and holds the value obtained by the accumulation after the engine is stopped, and a control means for heating a hot wire at a temperature higher than a temperature in the normal operation so as to burn off a deposit on the hot wire after the accumulated value in the memory means reached a predetermined value and the engines is stopped.

Fuel control apparatus

An air-fuel ratio controlling apparatus of an engine having an electronic control type automatic change gear ensures the expected acceleration feeling when a power mode is selected in the low load operation with a view to the start or the like of the automobile, and ensures the operation with emphasis upon the fuel cost. An air-fuel ratio adjusting means is provided to correct the air-fuel ratio to be richer during the low load operation of the engine when the power mode is selected than when an economy mode is selected.
