[EVERY NEWS 12] NISSAN MARCH / MICRA

Hi, this is Hina. I's getting warmer here but it's still chilly at night. I sometimes drives in fog on my way to home.

Today's car is NISSAN MARCH. Very poplar car in Japan and in the world. This car has been known that it has many different body type. There are MARCH Bolero and MARCH Rumba as classical version, MARCH Cabriolet as a drop head coupe, Wagon type as MARCH Box. And this vehicle also is used for a motor sport.

NISSAN MARCH (1989-now)

CVT AND ELECTROMAGNETIC CLUTCH OF MARCH K11
MARCH K11 model (The 2nd generation) have an electromagnetic clutch. It is different with a torque converter type clutch of latest cars. There seem to be many report of the electromagnetic clutch trouble.

The symptoms of this trouble is noise from the crutch. They said there is some possibility of relapsing even you replaced its CVT.

Some causes are conceivable, but one of this trouble is wearing down of a CVT brush. This part works to operate a electromagnetic clutch. A clutch slips and the vehicle can't move if the part is worn down.

On the other hand, in the case that has already occurred, engine oil leaked from a crank rear oil seal and come into a electromagnetic clutch. If you found heavy engine oil leaking, it is better to check its transmission and clutch carefully also.

POWER WINDOW
MARCH's power window glasses have plastic stoppers on the lower side of each glass to avoid glass fall down. If these stoppers are worn down and crack, they can't hold a glass and it will fall down. There are some possibility of wearing down of the part on all kinds of vehicles.

Unfortunately this plastic part is not provided separately as a brand new. So you may have to buy it as a glass assy if you want to replace it.

[EVERY NEWS 11] MAZDA DEMIO / MAZDA 2

Hi, everyone, this is Hina. It's completely spring season in Japan. Cherry blossoms are blooming one after another.

Today's EVERY NEWS is MAZDA car a long time after MPV. I have been seeing DEMIO on TV commercial many times these days because its new model debuted this month(April 2012).

MAZDA DEMIO
1996-now

POWER WINDOW TROUBLE
Sometimes I have heard the trouble of power window from 1st and 2nd generation DEMIO users (The newest model is 3rd generation now). Their condition is like the following.

Case 01 A power window can't be closed completely (A window glass moves down a little after it closed successfully).
Case 02 A window glass can up only 2~3 cm at once (It stops though you continue to push a power window switch).

DEMIO's power windows work with regulator motors with wires. Many vehicles have this types for regulator motors. But motors that have been used long time get weaker because of rust, wear,etc. Moreover, rubber gaskets on a lower of a window frame get stiffen. Then motor power yields to the friction of stiffed gaskets and a glass.

If its rubber gaskets get stiffed, window frames have strains, regulator motors may recognizes that something stuck between a window frame and a window glass. This is safety system. Not a fault of regulator motor.

SKYACTIVE ENGINE
This engine is the new engine manufactured by MAZDA. What is talked about is its compression ratio.

Compression ratio means the ratio of compressed volume of fuel-air-mixture in a cylinder.

The limitation of conventional gasoline engines' compression ratio is "12". If it over the limit, a knock would caused. But SKYACTIVE ENGINE broke the limit. It can up the compression ratio to "13~14" without a knock. "13" is said the ideal compression ratio for a gasoline engine. Then new DEMIO with SKYACTIVE's fuel expenses is 30km/1L.

The best fuel expenses car is still TOYOTA PRIUS(38km/1L), but SKYACTIVE is more simple construction and reasonable engine than PRIUS's TOYOTA Hybrid System.

Its power seems to be lower a little bit than old DEMIO's gasoline engine, but its fuel expenses is pretty great as a gasoline engine without electric motor.

SKYACTIVE should be worthy of note by all over the world.
