Abstract: An improved fuel supply arrangement for a direct fuel injected engine. In one feature, the fuel supply arrangement comprises a high pressure fuel pump for developing high pressure in fuel, a fuel injector for directly injecting the fuel into combustion chamber of the engine and a flexible conduit for connecting the high pressure fuel pump and the fuel injector. In another feature that is for a multi-cylinder engine, the fuel supply arrangement comprises a high pressure fuel pump for developing high pressure in fuel, a plurality of fuel injectors for directly injecting the fuel into respective combustion chambers of the engine, a fuel supply rail for supplying the fuel from the high pressure fuel pump to the fuel injectors and a flexible conduit for connecting the high pressure fuel pump and the fuel supply rail.

Abstract: A control method for controlling operation of an object used by a user in an environment includes the steps of: defining pseudo-emotions of the object for deciding output of the object, in relation to the user's state; formulating emotion generation algorithms to establish the relationship between the user's state and the pseudo-emotions; formulating behavior decision algorithms to establish the relationship between input, including the pseudo-emotions, and the behavior of the object; detecting the user's state; generating a pseudo-emotion of the object based on the user's state using the emotion generation algorithms; making the object behave based on the user's state and the pseudo-emotion using the behavior decision algorithms; evaluating reaction of the user in response to the behavior of the object; and if the reaction of the user does not match the pseudo-emotion of the object in the emotion generation algorithms, adjusting at least either of the emotion generation algorithms or
