Accuracy

Less than 10 days are left before Summer solstice, coming stuffy atomosphir this year.

It's very difficult to work outside under the circumstances.

Over 10 years of self-researching enabled me to come to an incredible level in the accuracy of scaling and adjusting on the wheel alignments and constructive geometry of the vehicle.

According to service manual the three dimensinal wheel inclinning values are shown as degrees and minutes units, but now my capable angle value is seconds !

I've found out that the incredible world is opend the day before yesterday while the adjusting on SXE10 Alteza.

Three pieces of Chimaki for ceremony that my intimate Chinese friend gave me remind me of sweetest days with a sweet heart in Shanghai 25 years ago, her name was Shaorinn, who was a graduate student of No2 Shanghai Medical School.

The taste and flavor of triangle rice ball remembered me many memories so clearly as if it was the affair happened yesterday.

As proverb says, "Every dog has his day.", I had my days at that time in foreign land, The People's Republic of China, this is the sweetest memory for myself never to forget all through my life.

Written in the evening:

Finding out the hysteresis in handle luck mount rubber adapter on NCP10 Vitz today, some countermeasure was applied. Insertion of 1mm thickness rubber seat between luck and adapter rubber far improved steering feel. Unexplainable strange reaction disappeared and fine clear reactions are obtained as another vehicles I'm keeping.

Battle

Some battle in the nature is observed this morning. A moth left side is alive fighting with small spider right side.
Though I wished to help it, deeper consideration made me do nothing, it's one of the phenomena, natural selection.

Abuse

Abuses caused by kids are unpleasant so much.They play baseball game on the public road with tennis ball with swinging bat.

The ball comes into my flower garden every day, kids coming into our private place without permission, devastating our nourishing flower plant.

Though I think it just a tiny happening by kids, they leave our gate fully opened without any apology, it's just for robbers ?

Basically the responsibility of these unprecedented behaviors by kind dues to their palent, so I think.

They sould know this is not the place for the game, better go to the ground in their school.

Judging from the existing of many geriatric nighbors swinging bat is dangerous enough, so stop before some irreparable accident occurs.

My opinion is out of orbit ?

Set Back error

The wheel alignment adjustments on NCP10 Vitz and EP82 Starlet have made me realize the importance of "Set Back". However precisely the alignments and geometry may be established, strange and unexplainable steering reaction is not possible to eliminate thoroughly if the existing of set back is ignored. Suppose the wheel bases on both side are so adjust to be the same value according to standard one with the condition of including set back error. The behavior itself is the same as producing "Swung Rear End" error.

So it is said that the initial step of wheel alignment is checking and examining the set back error in any case, otherwise the later efforts are all in vain however hardships may be overcome after that. It took me so long period of time this trifle but indispensable factor.

Today I'll re-examine the error of set back on SXE-10 Alteza.

Written in the evening:

The set back value plus 1,73 min(angle) was found on SXE10 Alteza, so left frontal lower arm bolts connecting with knuckle were loosened and re-tightened for adjusting in combination with toe adjustment.

Tight and solid steering feeling was increased in centric position after correction. The more precise wheel alignment leads to the more confidential and concrete steering stability.

Keep Machinery

Keeping machineries including vehicle need some adequate maintenances. So any devices could be kept unlimitedly if the maintenances are serviced enough. The same thing is said to family use electric furnitures. Consequently they in my house are relatively old over 10 years old. Someone in my house has some complaint because of old design. Probably the newer the better for house keeping person if the poorer performance it may be.

Motor performance

Obtaining best performance on 4cycle motor is one of the very professional work for vehicles. The engineers in factory make some desparate efforts to carry out their duties. They are salaried by the work, then is it possible to exceed them in the field for amature layman ? The answer goes without saying, no !

My son wants to replace the original muffler into 3rd party's one, how come ? He ignores the efforts by engineers without deeper considerations ? Even 4cycled motor has much to do with exhaust pressure in intimate relations with firing timing, of course he does not know, just enjoying different exhaust sound.

Some day he may realize himself that how premitive advertisments move his emotions now.

And there is no way to modify making completed vehicle better in any parts except correcting the assembling errors.

My graduated son called me last night noticing me about next voiage to 4 years program doctor course, costing 600,000 yen per year. It means my hard work is being prolonged for 4 years more. I must noursh him as long as 4 years more as a playing, not a studying, young man, how come ?

Firing timing

Setting fireing timing on otto-cycled motor is difficult reqireing experiences and keen sensitivity. Timing is advanced according to vacum pressure, motor's RPM and the speed of vehicle. Very precise rotating adjustment on distributor is necessary, deciding best position, actual running test driving in diferrent burdening are tried on several gear position.

The residual fuel amount affect the throttle response not a little. Hill climbing driving test may be the way. But computer fireing timing fully controlled vehicle is not capable to adjust basically, this is why recent sophisticated vehicle is not so interesting.

Direct cylindorical injection system needs strange piston top shape compareing with conventional motors, it's a relatively high wall for me to ride over.
