Aluminium Cylinder Blocks.The later Ds and the 'light weights' also had aluminium cylinder blocks sowere a very substantial departure from the production engine. There werealso some aluminium block race engines built to the 3 litre class ruleswith 85 x 88 mm bore and stroke rather than 83 x 91 (or 92) mm used withequivalent cast iron blocks. Initially head gasket failure was a problem,caused by the cylinder liners sinking and relaxing the gasket 'nip', butthis was cured by adding flanges to secure the liners at the top. Theoriginal aluminium main bearing caps proved to be inadequate and werereplaced by steel items but at the time an aluminium cylinder block wasquite innovative so some difficulties could be expected.By the standards of the time these were pretty powerful engines though theproject lacked the commitment of earlier days, and they never really cameto terms with Ferraris all conquering V12s. Once the aluminium block had been made reliable there were plans to developa production version and one or two 4.2 engines were built. They proved tobe unacceptably noisy and were abandoned after a short time. Fuel and SparksA number of carburetter arrangements were used over the years, the twin SUset up being the most common although the carbs themselves varied in type(H, HD, HS, HIF) and size over the years from 1.75 inch on the originalXK120 and most early saloon engines to 2 inch in later years as mostenthusiasts will know. 24 mm Solex down-drafts were used on most 2.4salthough 1.75 inch SUs were an option which became standard on the later240s and of course the MK10 and E Type had the triple 2 inch SU setup. Fromthe late 1960s emissions legislation in the USA meant that SUs in anyconfiguration had to be abandoned for that market, to be replaced by a pairof CD Strombergs with their greater accuracy and more sophisticated controlof warm up fueling. Accurate warm up fueling was never a strong-point forthe SU company - the electric choke devices used with their early carbswere barely satisfactory whilst the later AED was really pretty hopeless.Finally even the Strombergs were superseded by Bosch/Lucas L Jetronic FuelInjection which made it possible for the XK to meet ever tighter emissionregulations in the late 1970s using Lambda feedback of exhaust oxygencontent and a three way catalyst. This EFI system relied on air mass flowmeasurement rather than manifold pressure/speed as used with the V12 andthere was much debate about how best to apply the calibration measurementsfrom the test bed. It was not that there were errors in the work, just thatit could be interpreted in such a way as to introduce errors so that theoverall fueling could be about 4-5% richer than it should have been. Allthis was resolved however long before reaching production. A characteristic possibly unique to injected engines using the twin tanksystem of Jaguar series 2 and 3 saloons was that of weak back-firesindicating that a tank had run dry. On early development cars this couldblow the inlet elbow off the throttle thereby immobilising the car. Whenthis was made more secure these back-fires found the next weakness,slamming the airflow meter flap shut with sufficient violence to damage thepivot bearings. A spring relief valve mounted in the flap provedineffective and the cure was a rubber buffer for the flap to close against. Incidentally, the 4.2 EFI engine, aided by the largest of all productioninlet valves at 1.875', and rated at just 200 b.h.p. DIN (that meanscertified) was almost certainly the most powerful production XK ever. Onemight say that there was a degree of optimistic exaggeration about the 265b.h.p. claimed for the earlier triple SU engine which was never verifiedunder similar conditions. Less well known are those carburetter arrangements which never made itbeyond the experimental department. Various down-draft and side-draftconfigurations with as many as four carbs were tried but I understand thatthe most effective by far was a sort of reversed triple SU setup with longram-stacks extending out to three small plenum chambers from which thecarbs pointed inwards between the pairs of stacks. Apparently this even hadadvantages over the triple Weber setup used for racing but it lacked thetremendous visual appeal of the conventional triple SUs and was abandonedlargely for that reason. Another promising long ram system that did not seethe light of day was developed with the aim of giving the 2.4 a much neededtorque boost. Ram length has always been crucial to getting the best out of any Jaguarengine but sadly the production versions always seem to be compromised bythe available space. This was never the case with the racing XKs, otherthan very early ones with twin SUs, as would be obvious from a glance atthe long trumpets of the triple Weber and Lucas Injection (fig 6) systemsmentioned earlier. For many years ignition was by a conventional contact breaker but in 1978US emission engines began to use a version of Lucas OPUS, successful enoughin top level racing and a little troublesome on the Jaguar V12, yet not farshort of disastrous on the poor old XK. The act of cramming everythinginside the distributor body resulted in an unexpected sensitivity to heathaving the effect, if not of failing permanently, of periodically shuttingthe engine down for about 20 minutes until the critical components cooleddown again. OPUS was hurriedly replaced by the new Lucas Constant Energysystem featuring automatic control of coil current to give consistent sparkenergy over a wide range of engine speeds. This lasted until the end withcentrifugal and vacuum advance mechanisms so we never had the chance to seehow much the XK might have been improved by full electronic enginemanagement.

A 1.5 L version of the EcoBoost engine family was first unveiled in the 2014 Ford Fusion as a downsized version of the 1.6 L EcoBoost engine. The downsized displacement is a result of Chinese vehicle tax regulations which tax vehicles with engine displacements of 1.5 L or less at lower rates.

Xversion 1 3 6 Cylinder Misfire
The General hasn't produced a three-bonker for the U.S. in nearly 20 years.
Always on the hunt for better fuel economy, General Motors is reviving the three-cylinder engine for future models in North America. It's the first time GM has offered a three-pot stateside in nearly two decades.
A pair of new engines will surface in the 2021 Chevrolet Trailblazer and next-gen 2020 Buick Encore GX, displacing 1.2 liters and 1.3 liters. They are based on similar versions revealed abroad, although power ratings for U.S.-bound engines aren’t available just yet. Given their relatively modest subcompact applications, don't expect them to suck you into the seat.
That said, some innovative tech and turbochargers will provide extra boost, allowing the new mills to create power similar to their four-cylinder counterparts while reducing fuel consumption. Such tech includes an electrically assisted wastegate system, an electrically driven water pump, and an active vacuum system to help relieve parasitic load on the engine. Because they feature newer tuning, weigh around 40 pounds less, and have one fewer cylinder, they'll likely score better fuel economy numbers and emit fewer emissions than the equivalent four-cylinder engines they replace.
One of the latest versions of GM’s 1.3-liter Ecotec made its debut in the Korean-specification 2019 Chevrolet Malibu, producing 156 horsepower and 174 pound-feet of torque. That's about on par with the Encore’s former top-spec 1.4-liter turbo four, which made 153 hp and 174 pound-feet. Buick discontinued that engine option for the current Encore in its last year of production before the second-gen's arrival in early 2020. The new three-cylinders are expected to produce similar power.
The Detroit giant has been offering three-cylinder engines since the mid-1980s, but not always for the U.S. market. Previously, GM had offered a three-smasher in North American-spec Chevrolet and Geo Metro models, although those were killed off following the 2000 model year. The Metros featured a naturally aspirated, 1.0-liter mill, developed with Suzuki, that produced 55 hp.
Since then, GM has teamed up with its former Opel subsidiary (now owned by PSA), the Shanghai Automotive Industry Corporation (SAIC), and MG Motor to produce a new Ecotec inline-three for subcompact Opel, Vauxhall, Chevrolet, and Buick models in overseas markets. The new three-cylinder engines will reportedly be built at GM's plant in Mexico alongside other North American market GM vehicles.

Chevrolet's arch rival Ford, with its 1.0-liter EcoBoost, is the most recent American manufacturer to offer a three-cylinder engine in the U.S. Ford dropped that engine from the now-extinct Fiesta and Focus sedans, but it lives on in the EcoSport subcompact SUV. BMW also has a small-displacement three-pot in its lineup that often shows up under the hood of various Mini models.
