Description
技术领域technical field
本发明涉及的是一种发动机装置及其控制方法。The invention relates to an engine device and a control method thereof.
背景技术Background technique
相继增压技术是指采用两台或者多台涡轮增压器，根据柴油机运行工况的不同，使用不同数量的涡轮增压器与之并联运行，是改善高增压柴油机低工况性能的有效方法，具有结构简单，可靠性高，易于在现有涡轮增压柴油机上实现的优点，目前已经得到越来越广泛的应用。Sequential supercharging technology refers to the use of two or more turbochargers. According to the different operating conditions of the diesel engine, different numbers of turbochargers are used to run in parallel with it. The method has the advantages of simple structure, high reliability, and easy implementation on existing turbocharged diesel engines, and has been more and more widely used at present.
相继增压切换延迟时间是确定相继增压的关键技术之一，随着柴油机转速和负荷的增压，相继增压系统中的燃气阀和空气阀先后打开，受控增压器投入运行。在切换过程中，由于增压器自身转速惯量等因素，受控增压器无法立即响应投入工作，即具有滞后性，所以燃气阀必须先于空气阀一定时间打开，防止切换过程中受控增压器发生喘振。但是，由于燃气阀的开启，使基本增压器的废气流量瞬时减少，而空气阀需延迟一段时间再开启，这期间受控增压器无法向发动机提供增压空气，造成发动机转速波动、运行不平稳等不良现象。The switching delay time of sequential supercharging is one of the key technologies to determine the sequential supercharging. With the boosting of diesel engine speed and load, the gas valve and air valve in the sequential supercharging system are opened successively, and the controlled supercharger is put into operation. During the switching process, due to factors such as the speed inertia of the supercharger itself, the controlled supercharger cannot immediately respond to work, that is, it has a hysteresis, so the gas valve must be opened for a certain period of time before the air valve to prevent the controlled supercharger from The compressor surged. However, due to the opening of the gas valve, the exhaust gas flow rate of the basic supercharger is reduced instantaneously, and the air valve needs to be opened after a delay for a period of time. Unevenness and other bad phenomena.
由于具有快速的响应特性和灵活的工作方式，电辅助涡轮增压技术逐渐收到关注并进入研发过程。当低速大负荷、加速工况时，电机启动驱动压气机工作，电能转化为压气机的动能，以提高进气压力；当发动机工作在高速或大负荷时，电机关闭，发电机启动，回收涡轮能量中一部分转化为电能。电辅助增压主要有三种实现方式：电机前置、电机中置以及电辅助增压器独立布置。Due to its fast response characteristics and flexible working methods, electric-assisted turbocharging technology has gradually received attention and entered the research and development process. At low speed, heavy load, and acceleration, the motor starts to drive the compressor to work, and the electric energy is converted into the kinetic energy of the compressor to increase the intake pressure; when the engine works at high speed or heavy load, the motor is turned off, the generator is started, and the turbine is recovered Part of the energy is converted into electricity. There are three main implementation methods of electric assisted supercharging: front-mounted motor, mid-mounted motor, and independent arrangement of electric-assisted supercharger.
目前已授权或公开的专利中，涉及到电辅助增压涡轮增压器的较多。如申请号为“200720017195.X”的“电辅助涡轮增压器”专利，提供了一种电辅助涡轮增压器，将电辅助装置设置于压气机壳的进气口外侧，以克服涡轮增压器高温对电辅助装置的限制，但是该电辅助装置改变了增压器的平衡，会产生振动问题，对增压器工作不利。申请号为“200820225752.8”的“一种电辅助涡轮增压器”，在专利“电辅助涡轮增压器”的基础上，在电磁转子与压气机叶轮之间设置了转子轴承支撑装置，以此来消除增压器轴系不平衡带来的振动问题。但是由于电机转子与涡轮增压器连接轴固连在一起，涡轮增压器长时间高速运转会降低电机的运行性能，类似将电辅助装置与涡轮增压器集成一起的方案值得进一步改进。同时，上述专利均是把电辅助增压技术单纯运用在涡轮增压器上，旨在解决全工况的理想匹配和涡轮滞后效应。Among the patents that have been authorized or published at present, many of them relate to the electric auxiliary supercharging turbocharger. For example, the "electrically assisted turbocharger" patent with the application number "200720017195.X" provides an electrically assisted turbocharger. The electric auxiliary device is arranged outside the air inlet of the compressor casing to overcome the However, the electric auxiliary device changes the balance of the supercharger, which will cause vibration problems, which is not good for the operation of the supercharger. The application number is "200820225752.8" for "an electric assisted turbocharger", on the basis of the patent "electrically assisted turbocharger", a rotor bearing support device is set between the electromagnetic rotor and the compressor impeller, so that To eliminate the vibration problem caused by the imbalance of the supercharger shafting. However, since the rotor of the motor is fixedly connected to the connecting shaft of the turbocharger, the long-term high-speed operation of the turbocharger will reduce the performance of the motor. The scheme of integrating the electric auxiliary device with the turbocharger deserves further improvement. At the same time, the above-mentioned patents are purely applying the electric-assisted supercharging technology to the turbocharger, aiming to solve the ideal matching and turbo lag effect under all working conditions.

When the cut-out condition of the controlled supercharger is met, the gas valve and air valve are closed at the same time, and the vent valve is opened, the control motor is combined with the controlled turbocharger, and the inertial force of the controlled supercharger running at high speed is used to drive the motor The accumulator is charged, so far the controlled supercharger is cut out smoothly.
首先分别采集基本增压器和受控增压器转速传感器的转速信号以及压力传感器的压力信号，若不满足切入条件，切换不进行，电机不启动，燃气阀、空气阀以及放气阀均呈关闭状态，受控增压器不工作，同时电机转子与受控增压器连接轴保持结合状态；若满足切入的条件，同时打开放气阀和空气阀，并启动电机，电机带动受控增压器高速运转；判断基本增压器和受控增压器转速传感器的转速，若两者的相对误差高于10％时，维持电机继续工作；若两者相对误差低于10％时，再判断基本增压器和受控增压器压力传感器的的压力是否相等，若不相等，则维持电机继续工作，若相等，则控制离合器使电机与涡轮增压器分离并关闭电机，至此受控增压器顺利切入进行工作；继续采集基本增压器和受控增压器转速传感器的转速信号以及压力传感器的压力信号，若满足受控增压器切出条件时，同时关闭燃气阀和空气阀，并打开放气阀，控制电机与受控涡轮增压器结合，利用受控增压器高速运转的惯性对蓄电池进行充电，至此受控增压器顺利切出。First, collect the speed signals of the speed sensors of the basic supercharger and the controlled supercharger and the pressure signal of the pressure sensor. If the cut-in conditions are not met, the switching will not be performed, the motor will not start, and the gas valve, air valve and air release valve will all be in the state of zero. In the closed state, the controlled supercharger does not work, and at the same time, the motor rotor and the connected shaft of the controlled supercharger remain in a combined state; The compressor runs at high speed; judge the speed of the speed sensor of the basic supercharger and the controlled supercharger, if the relative error between the two is higher than 10%, keep the motor to continue to work; if the relative error between the two is lower than 10%, restart Determine whether the pressures of the pressure sensors of the basic supercharger and the controlled supercharger are equal. If they are not equal, the motor will continue to work. If they are equal, the clutch will be controlled to separate the motor from the turbocharger and the motor will be turned off. The supercharger cuts in smoothly to work; continue to collect the speed signals of the speed sensor of the basic supercharger and the controlled supercharger and the pressure signal of the pressure sensor. If the conditions for cutting out the controlled supercharger are met, the gas valve and the air valve, and open the vent valve, control the combination of the motor and the controlled turbocharger, and use the inertia of the controlled supercharger to charge the battery at high speed, so far the controlled supercharger is smoothly cut out.
