There are so many caravans on the roads now days sprint it's unbelievable
Just a couple of observations about keeping machinery functional Always have a can of inox in the boot and spray all your suspension once a week to keep the rust off it Inox is cheap and suspensions are expensive Spray all around the electronic braking system Don't drive your caravan through creek crossings with hot bearings or heated up brakes Spray all around your jockey wheel your shackles and towball Make sure you have a good trailer braking system and make sure it is adjusted correctly for the weight you are towing Don't tow heavy loads with 4 cylinder turbo diesels You can't be cubic centimetres for towing ability And no that does not mean by a dodge ram They are rolling piles of junk |

I would take some contest with some of your statements.
But not towing with a 4 cylinder diesel, that's just incorrect. I have an Isuzu mux, it has a 4 cylinder engine and is designed to tow. The exact same engine is fitted to the dmax and the 8 ton truck. The engine cylinder configuration has little to do with towing ability, and as technology is increasing, so is the performance. Now, I'm not a person who believes the Nissan and Ford variants with 2.2 litre engines is a long term prospect. But the good old Isuzu 3.0 litre turbo has been hauling vans all over the world for many years. My old Nissan x trail ( a 2.5 litre 4 cylinder petrol) capably towed my 1.5 ton plus boat around all over the place, never an issue, never missed a beat. The real trick is the gearbox. Newer diesel cars have 6 or mode gears and the autos are all particularly strong. I just put it in drive and go. Manual gearboxes are only better in that they do not tend to overheat as much as auto, but a good tranny cooler rectified that. I have been towing boats and trailers for over 40 years. If you use the gearbox correctly and drive sensibly, even a 1.5 litre 4 cylinder echo can tow with no problems, within it's limits of course. |

yes, technology has changed
I am becoming more amenable to a higher tech motors. Their advantages far outweigh any concerns. The new Mitsi 2.4 litre diesel. http://mmc-manuals.ru/manuals/l200_v/online/Service_Manual/2017/11/html/M211200010266000ENG.HTM Great torque from 1600 --> 2700 rpm. It'll rev beautifully, mated with an 8 speed Aisin Auto transmission. |

Long stroked engines have a high wear component on the thrust side of the cylinder, they also can't rev as hard as a short stroke, the speeding up and slowing down of the reciprocating mass will break it if it spins too fast. The advancement in lubrication is what allows modern engines to be as good as that are. You will get more torque from a long stroke as the power cycle lasts longer and has a greater leverage via the crank throw. No matter the engine it's the lubrication that keeps it alive. |

rubbish, the 2.5 litre turbo diesel in the triton is virtually unchanged since 2010. i would have said wait a few years in 2010 until they iron out any flaws. the early ones had a lot of carbonated intakes. they ironed this out in 2012 and its been reliable ever since. so you have 10 years of proven technology in a car which is number 10 on the sales figures for oz. so , yes buy one. they are proven old school technology with a long model run. if mistsubishi tried to appeal tio numpties (like you) and brought out a new engine for 2022 then i would say wait until they iron out the problems let numpties like canyons be the guinea pigs. as for aisin gear boxes. they are owned by toyota ::) ::) please find where aquascoot has been anythiong other then supportive of toyota ::) |

Title: Re: Using low gears in an auto Post by aquascoot on Jun 21st, 2021 at 12:16pm
High technology in motor vehicles is being driven by two factors
Firstly the Europeans have very very strict fuel economy and emission standards and so a lot of extra garbage has to be put on the vehicles to try to meet those standards Including a lot of recirculating hot exhaust gases which of course heats up the engine even further as well as recirculating particulate matter through the engine and the valves and this makes engines failed earlier VW admitted this themselves When they faked their emissions readings to try to get engines approved Strict standards and engine longevity are not mutually compatible The second problem is that it is a lot easier and cheaper for the manufacturer is to run as many systems as possible using electronics This ties the consumer to the manufacturer as the consumer does not have the software And it also means that expensive computerize systems As in expensive to work on and replace Are running things which is to be run reliably through mechanical methods A computerized system to run the handbrake on an Audi Quattro costs $1,500 to replace when it fails Previous to that you could buy a length of wire for $3 and fix the handbrake yourself |

low tech....good for a long lasting reliable vehicle that you can service yourself and save money high tech....good for corporations and governments as you have a vehicle which will require a lot of workers to service the regular breakdowns thus creating a lot of economic activity. the disposable society is much beloved of corporations and governments . think of cars now in the way you think of phones. high tech peices of kit which you cannot work on and which you just junk every 5 years and buy a new one. not my idea of common sense but good for the unthinking masses like yourself who are impressed by machines that go ping ::) ::) ::) |

Compared to what you seem to like, yes it is.
Variable geometry turbo, variable valve timiing (first in a diesel) To meet the requirements of global emissions standards, Mitsubishi developed a new catalyst system that combines a Diesel Oxidation Catalyst (DOC), NOx Trap Catalyst (NTC) and Diesel Particulate Filter (DPF).[1][11] |

you appear confused. i'm not recommending the mitsubishi engine over the 2.8 litre 2L hi lux engine of the 90's BUT if an engine has been unchanged for over a decade then it fits my description of "not the latest, greatest, most over engineered technology" ::) ::) ::) |

I drive a small car. Going up Mount Archer, I will stick to using the automatic transmission. But, coming down the hill, I have to put the transmission into 2nd gear. I learned a long time ago that your brakes overheat from overuse.

High tech doesn't always mean better
The electric power steering on my 2016 Kia Cerato is the worst steering I've ever experienced. I've owned a lot of different brand cars over the years, but this Kia has only done 35,000ks and still under warranty, previous elderly lady owner The steering is stiff and notchy at speeds above 40kh, the Kia dealer said it's normal. I fitted brand new tires and over-inflated them from 32 to 38, got the wheel alignment checked and adjusted, but still there's a "stiff" feel to the steering. This is not high-tech, it's just bullshit My old Corolla was heaps better and it had no power steering at all. That Corolla also had an Aisian auto, said to be 3sp, but it had a 4th gear overdrive that you never knew it had unless you carefully listened to the revs or felt the very slight hesitation of the car when going up a grade. Never felt it go into that gear though, there was no switch for it. I miss that gearbox, it was pretty good The Kia has high-tech stuff for the engine, brakes, millage read-out and other sensors, but the rest of the car is very ordinary. The door catches and handles act like, and are no better than old Kelvinator fridge doors, before magnetic door seals. The hatch door opens and closes a bit like a tilting garage door and if it's not closed fully, the battery goes flat, you may not know. The bonnet must be slammed down to shut it, gently pushing it down will dent the sheet metal because the bonnet is that hard to close. You can feel every change from the auto box most of the time, and the curved side rear-view mirrors give a false impression of how far traffic is away from you ... and then there is the terrible power steering, not worth a pinch One saving grace is the low fuel consumption, but only if driven at moderate speeds, fast speeds on or over speed limits just ruins fuel economy, it's then equal to my 3.0L diesel van However, on one long stretch on the way home from town, I get 4.3 Lts/100ks from the Kia, but that's in 5th gear, not 6th, and doing 70-80 kh. 5th gear takes load off the motor and the accelerator pedal is not pressed down as far, so not as much fuel is needed. The 4.3 was displaying on the dash millage computer read-out. The engine is a 1.8lt, so, not bad in that regard |

I didn't say it was For lowering fuel consumption it's been very beneficial to reduce pollution and for cost saving ... but for electric power steering, they might as well go back to hydraulic power steering, it was easy smooth steering at all speeds, and if it failed, the vehicle can still be steered without a lot of extra effort, much safer than electric steering |

They can be, a modern 6 with it's design and lubricants will do a lot more miles than the 80-100k miles you would get out of a Holden red 179 EH. VW had to cheat because their engine wasn't up to scratch for modern standards. Running an engine lean for eg when it's on test or at any time will cause heat, wear and oil breakdown. BTW, I do not know what VW did to fudge the tests but I'd suspect the ECU could detect testing to a degree or they could be switched to it. |

various scams like "stop start " technology to turn the engine off at a red light or shutting down 1/2 the cylinders in a 8 or 6 are designed to try to get good figures to pass european emssions and fuel consumption tests. they are probably bad for the engine. and a few dollars saved in fuel is nothing compared to reduced longevity |
