Abstract: An instantaneous type fuel-fired water heater has a variable speed blower that discharges combustion air into a fuel burner utilized to heat water flowing through a heat exchanger portion of the water heater.

In this manner, such flue gases are cooled by the bypassing blower discharge air to an extent permitting the flue portion to be formed from a low cost plastic material instead of a high temperature metal material such as stainless steel.

Abstract: If it is determined that an engine has been started, an engine coolant temperature is detected. If the engine coolant temperature is equal to or lower than a threshold value, the catalyst quick warm-up control is started to retard ignition timing, and a signal indicating a command to increase an operate angle is transmitted to a VVLA controller.

Abstract: An idling stop control of the invention attains an auto start and an auto stop of an engine. At a time point t1, pre-set stop conditions are met to cut off a fuel supply to the engine. Preset starting conditions may be met at a time point t2 when the engine still continues rotating in a normal direction by the inertial force. In this state, the idling stop control starts cranking the engine. The preset starting conditions may be met at a time point t4 when a piston does not complete a compression cycle immediately before a stop of the engine but is pressed back by the compressed air to rotate the engine in a reverse direction. In this state, the idling stop control waits until cancellation of the reverse rotation of the engine and then starts cranking the engine. The arrangement of the invention desirably ensures a quick start of the engine, while effectively preventing an excess stress from acting on a gear mechanism, which connects a starter motor to the engine.
