Abstract

The embodiment of the invention discloses an engine development test work condition information acquisition method and device. The engine development test work condition information acquisition method comprises the steps that automobile emission or fuel consumption testing is performed; and the work condition information of an automobile engine in testing is acquired so that engine development testing can be performed based on the work condition information. According to the engine development test work condition information acquisition method and device, the work condition of the engine is acquired according to the complete work condition of the automobile obtained through automobile emission or fuel consumption testing so as to acquire the work condition of the engine close to that of the actual use of the automobile of the user, and thus the method and the device are used for engine development testing.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a method and a device for acquiring working condition information of an engine development test. Background technique [0002] During the engine development process, some tests require the operating conditions of the engine to be close to the operating conditions of the user's actual use of the vehicle. However, in the current engine development test, the working conditions of the engine are simply described by using a set of empirical data to simulate the working conditions of the engine when driving a vehicle on roads such as urban roads, suburban roads and expressways. [0003] A set of empirical data commonly used in engine development experiments to describe engine operating conditions is as follows: [0004] 1) The speed of the engine is 1500-2000 rpm, and it runs at half load for 0.5 hours, which is used to simulate the working conditions of the engine when driving a ...
