Does the 20r motor have computer in it?

Just to see if it would last after a emp.

Not as far as I know - but it's not really relevant.

An actual EMP as generated by a nuclear attack will damage anything with electrical parts at close range.

A bit further away, it's more likely to just damage semiconductors.

An old diesel that has a mechanical injection pump would not be affected much by the EMP.

However, anything near enough to be damaged by the EMP effect from a nuclear attack will also rendered radioactive, if not destroyed outright by the nuclear blast.

A deliberate high-altitude EMP attach can affect things at fairly long distances - but only such as power cables from power plants etc.

EMP is a very short-range effect when it comes to 'small' items such as vehicles, only a few miles even with the energy from an atomic bomb behind it.

The main damage produced in nuclear EMP testing has been to infrastructure - pickup by massively long (tens or even hundreds of kilometre) power and phone cables between exchanges.

They act as antennas and can be affected by a nuclear EMP at hundreds of miles.

The range of the effect is proportional to the length of the metal wire / cable / item picking it up.

Soviet tests found they had to segment long cables down to _25 miles_ or so per section, with protective devices between sections, to limit damage.

Laboratory or DIY EMP devices do nothing more than generate a static "click" on radios just a few yards away - lightning strikes produce massively stronger EMP effects than electrical EMP machines & they don't shut things down without a direct hit (or if they burn out a powerline)..

All that is ignoring the fact that most vehicles have a steel bodyshell (ie. iron based) which protects everything inside it from external electrical or magnetic fields - it acts as a "Faraday Cage".

A car can be struck by lightning and the people in it are completely unaffected.

EMP will fry ANY electrical circuit that is on at the time and even some sensitive computer chips even when off. Diesel engines (old type not with turbo) can be started even without a battery and are therefore EMP resistant.

An emp will induce a huge flow of current through any coil. If the coil can withstand the pulse the next component down the line gets affected.

We need the year and model car that the 20R engine came in. If it has fuel injection it would have. Not sure about 20R engines with carburetors.

Take your VIN code to any Toyota Dealers parts counter. They'll run the vin code through factory records and be able to tell you in minutes if the car has a computer.

No motor in a car has a computer in it. Is this a trick question? The computer is either in the engine compartment or in the interior!

No computer, but it has a battery to start it, and a solenoid and a capacitor here and there.

the old toyota 20 r? with efi, it had a computer.

sandokan said it doesn't
