도 1은 본 발명에 의한 터보차저 엔진을 나타내는 도면이며, 도 2는 본 발명의 터보차저의 손상방지를 위한 경보장치의 상세도이다.1 is a view showing a turbocharger engine according to the present invention, Figure 2 is a detailed view of the alarm device for preventing damage of the turbocharger of the present invention.

도면중 부호1은 터보차저이며 실린더(2)에서 연소되어 배출되는 배기가스의 유동에너지에 의해 회전하는 터빈(3)과 블로어(4)가 회전축(5)의 양단에 설치되어 있다.In the figure, reference numeral 1 denotes a turbocharger, and turbines 3 and blowers 4 which are rotated by the flow energy of the exhaust gas combusted and discharged from the cylinder 2 are provided at both ends of the rotary shaft 5.

상기 블로어(4)가 회전하여 에어크리너(6)를 통해 외부공기 도입을 안내하는 흡기관로(7)의 도중에는 부압체크센서(8)가 설치되어 있다.The negative pressure check sensor 8 is installed in the middle of the intake pipe path 7 through which the blower 4 rotates to guide the introduction of external air through the air cleaner 6.

상기 부압체크센서(8)는 흡기관로(7)에 연통하도록 설치되는 절연체인 하우징(9)과 하우징(9) 내부를 다이어프램실(10)과 대기압실(11)로 구획하는 다다이어프램(12) 및 이어프램(12)이 흡기관로(7)에 형성되는 흡기부압에 의해 이동하게 될 때 회로를 온 접속하는 스위치기구(13)로 구성된다.The negative pressure check sensor 8 includes a diaphragm 12 which divides the housing 9 and the inside of the housing 9 into the diaphragm chamber 10 and the atmospheric pressure chamber 11, which are installed to communicate with the intake pipe path 7. ) And a switch mechanism 13 for connecting the circuit on when the ear ram 12 is moved by the intake negative pressure formed in the intake pipe path 7.

상기 스위치기구(13)는 하우징(9)에 고정되는 고정접점(14)과 상기 다이어프램(12)에 고정되어 함께 이동하는 가동접점(15) 및 상기 가동접점(15)을 복귀하는 방향으로 잡아당기는 리턴스프링(16)과로 구성되며 스위치기구(13)가 온 접속되면 점등되는 경고등(17)이 운전석 계기판에 마련되어 있다. 미설명 부호 18은 대기에 개방된 구멍이다.The switch mechanism 13 has a fixed contact 14 fixed to the housing 9 and a movable contact 15 fixed to the diaphragm 12 to move together and pulls the movable contact 15 in a returning direction. The warning light 17 which consists of the return spring 16 and is turned on when the switch mechanism 13 is connected on is provided in the driver's seat instrument panel. Reference numeral 18 is a hole open to the atmosphere.

이와같은 본 발명은 실린더(2)로부터 배출되는 배기가스의 유동에너지에 의하여 터보차저(1)가 구동되면 에어크리너(6)를 통해 흡입되는 공기를 가압하여 실린더(2)에 급송하게 된다.In the present invention as described above, when the turbocharger 1 is driven by the flow energy of the exhaust gas discharged from the cylinder 2, the air sucked through the air cleaner 6 is pressurized and fed to the cylinder 2.

그러나 에어크리너(6)가 먼지 등의 이물질로 막히거나 기타 다른 요인으로 인하여 공기의 흡입이 원활하게 이루어지지 아니하면 블로어(4) 회전구동에 의해 흡기관로(7)내에는 강한 흡기부압이 형성된다.However, if the air cleaner 6 is clogged with foreign matter such as dust or other factors, the intake pipe 7 is formed in the intake pipe 7 by the rotational operation of the blower 4. do.

흡기관로(7)내에 기준치 이상의 흡기부압이 형성되면 다이어프램(12)의 이동량이 커지게 되며 이에따라 가동접점(15)이 다이어프램(12) 이동에 연동하여 하강하여 고정접점(14)에 접촉하여 경고등(17)에 밧데리 전원(19)이 공급되어 점등되어지게 된다.If an intake negative pressure greater than the reference value is formed in the intake pipe 7, the amount of movement of the diaphragm 12 increases, and accordingly, the movable contact 15 descends in conjunction with the movement of the diaphragm 12 to contact the fixed contact 14 to warn the warning lamp. The battery power source 19 is supplied to 17 to be turned on.

따라서 운전석 계기판의 경고등(17)의 점등을 보고 운전자는 터보차저의 손상방지 및 배기가스 악화를 방지하기 위하여 에어크리너(6)를 비롯한 흡기계를 점검하여 에어크리너(6)가 수명을 다하였으면 교체해주는 등 필요한 조치를 취하게 되는 것이다.Therefore, in order to prevent the damage of the turbocharger and the deterioration of the exhaust gas, the driver checks the intake system including the air cleaner 6 and replaces the air cleaner 6 when it has reached the end of its life. You will take necessary measures, such as by making it happen.

이상과 같은 본 발명에 의하면 에어크리너가 막히게 되면 터보차저의 블로어에 이르는 흡기관로에 강한 부압이 형성되는 것을 이용하여 그 부압이 기준치 이상일 때 회로를 접속하는 스위치기구를 마련하여 경고 등을 점등시키므로써 에어크리너의 교환시기를 적기에 알수 있으며 에어크리너 및 흡기관로의 이상을 방지하여 터보차저가 손상을 입거나 배기가스 악화를 가져오는 일이 방지하는 효과가 있다.According to the present invention as described above, when the air cleaner is blocked, a strong negative pressure is formed in the intake pipe path leading to the blower of the turbocharger, and when the negative pressure is higher than the reference value, a switch mechanism is connected to the circuit to light the warning lamp. The time to replace the air cleaner can be known in a timely manner, and the air cleaner and the intake pipe can be prevented from being damaged, thereby preventing the turbocharger from being damaged or deteriorating the exhaust gas.
